ball rolling down a ramp experiment lab report For a rolling object, kinetic energy is split into two types: translational (motion in a straight line) and rotational (spinning). Measure the velocity of a ball using two Photogates and computer software for timing. Set up a 5m runway with a ramp at one end that raises 20cm. Measure distance from bounce 1 to bounce 2. You will use this information and your knowledge of physics to predict where the ball will land when it hits the floor. There should already be 20 cm. 6. Newton's second law for motion along the x-axis: f s −Mgsinθ=Ma com (eq. According to Galileo it would not matter about the inclination (slope) of the two ramps. In this experiment we are going to use a projectile launcher to vary the angle of release for a piece of. time would show these changes. For a ball rolling down an inclined plane, this acceleration relates to the gravitational acceleration g via. You will use this information and your knowledge of physics to predict where the ball will land when it hits the floor. Lower and raise the ramp to see how the angle of inclination affects the parallel forces acting on the file cabinet. Place a masking taper I am performing an experiment in which a dynamic physics cart will be rolling down an inclined plane (at an angle of about 5 degrees). You could also do this experiment on a ramp. EJOURNAL REPORT 6. Think about this: if the track was inclined to 90O the ball would drop straight down and the acceleration of the ball would be equal to “g”. • Will only consider rolling with out slipping. And that energy levels are eventually distributed uniformly. The stationary ball is well aligned with the incoming ball as far as height is concerned Ramp was position so that it launches the ball horizontally. I think ~ An object´s mass decreases velocity. In this lab exercise, you will see how the acceleration of a cart depends on the ramp angle. As with any moving object on Earth, there will be friction that prevents this. 2 Materials and Methods For this experiment, we utilized a Kirkland Signature Water Bottle (See Figure 2) as the rolling object. Thus: Total Energy = Kinetic Energy + Gravitational Potential Energy (1) E =K. 17. For our experiment, it is important to understand that acceleration is defined as, "the rate at which velocity changes. Roll the ball down the ramp, through the photo gates, and catch the ball before it hits the ground. 3. Lab report for Projectile Motion Lab. Take a practice run with your tennis ball. Remember The Ball Is Rolling Without Slipping!! Design Your Experiment Within The Range Of Materials Provided. Next, place an object like a smaller book at the end of the track to prevent the A longer and less steep ramp should be used to make it easier to accurately measure the travel time of the car. Method 1: Measure carefully the mass m and radius r of the ball-bearing and determine its moment of inertia using the expression: 2 5 2 I = mr (13) Ensure you answer contains estimates on the error in I. EXPERIMENT 4 PROJECTILE MOTION I. In this video you will see a ball released at the top of a ramp. From the ramps top we count down and release, which at the same time we start counting time and stop at the time when I hear the ball hit the floor. (1) To study uniformly accelerated motion in the case of a freely falling body. Variables Input/Control Outcome Units Height of Ball from the ground Height of Ramp Distance ball rolls Centimeters (cm) Length of Ramp Speed ball rolls Surface of Ramp Direction ball rolls Use the stopwatch to time how long it takes for the ball to slide down the ramp. Elmo's fire. Students will be able to see the relationship between mass and work done on the cup and/or ramp height and work done on the cup. In this case the situation is similar to the case with no ramp, the ball gains a kinetic energy and the velocity can be computed as before. Elmo's fire. The students mark off the position of the marble after 1 s, 2, s, 3 s, and 4 s. If a cart is initially at rest, it falls vertically a distance h as it travels down the track (Figure 2). Suggested practical - investigating acceleration down a ramp Investigate the acceleration of a trolley down a ramp. When the marble is released at the top of the ramp, the ball doesn’t have the same momentum as it does towards the end of the ramp. One timer will always find the time the ball takes to move through the last 20 cm of the ramp. Because kinetic energy is calculated from the mass of an object and its speed, the higher the ramp, the faster an object rolling or skidding down the ramp will be The purpose of this lab is to prove the conservation of linear momentum. { \Velocity of a ball rolling down a hill vs. Angle 2: Info: Ramp is 1. Start the graph on the LabQuest and let the marble go. The relationship between distance traveled and time was not linear. Start data collection. First, we rolled the truck down the ramp with the bed empty, and then we filled it with rocks and tried it again. The idea is that if you put a solid object on a ramp and start to tilt the ramp upward, there is a point where the object will start to slide. You will record the time it takes the ball to roll down the incline every 20 cm. If not, you must do so in order to. A graph of its velocity vs. The momentum of the system before and after the collision will be compared. 0 cm mark on the ruler. 2) Set up the equipment as shown in in class. In the following activity, students analyze the motion of a ball rolling down a ramp, similar to Galileo's experiment. Am I right please help The goal of this experiment is to measure the static sliding coefficient of friction between two surfaces by using a ramp and measuring its inclination. Test to see that the steel ball will roll straight but do not allow it to drop off the table. Be sure to smooth the ramp transition with the runway with a taped firm piece of paper. For a disk or sphere rolling along a horizontal surface, the motion can be considered in two ways: We can see this from our lab results from the average speed of the marble traveling down the ramp, because it picks up speed. 2. These are intended for students to learn skills such as changing one variable at a time, clearly recording and representing observations, and making accurate observations without mixing them with explanations. Be sure to include the angle in your lab report data table. ” Determine experimentally the minimum height h such that the ball loops the loop without leaving the track. Open the file 08 projectile motion on Logger Pro. If students are provided with a large assortment of objects and options to create the inclined plane, they are given more 1. Students will roll the balls down the ramp into the cup and measure how far the cup moves. A ramp of "Aesop’s Fables II" served as the inclined plane. If you continue browsing the site, you agree to the use of cookies on this website. there is no friction between the ball and the ramp) the ball just slides down the ramp, note that it does not turn at all, it just slides. See the diagram below. • Start MacMotion by double-clicking its icon on the desktop. PROCEDURE Set up a ramp as shown in Figure 1 that will be our inclined plane. Merrily We Roll Along Lab Report 862 Words | 4 Pages. This description will serve as a prediction before collecting experimental data.

Write a problem statement that makes sense and . PARTICLE TECHNOLOGY LAB REPORT 33 Procedure of Ball Mill Measure the inside diameter of the ball mill. Allow a tennis ball to roll down the ramp freely. The cube slides without friction, the other objects roll without slipping. The ball was rolled down the ramp and the impact point was noted. From this measurement (and its uncertainty), determine the k factor of the ball (and the uncertainty on k). Place a masking taper marker where the ramp touches the floor and label 0m. Newton (1642-1727) OBJECTIVES To derive and test a model of rolling with slip. A. 5 meters and 1 meter. Please CATCH the cart when it reaches the end of the incline, do NOT allow it to crash to the floor! I'm in grade 11 physics and we were just told to create and carry out a conservation of energy lab and do a report. LABORATORY REPORT. An object´s momentum increases with velocity. Place the bottom section of a milk carton at the bottom of the ramp to catch the marble and measure the distance that it moves the carton. I explored further into this principle by rolling a ball down an inclined plane covered with different textures to see if texture affects the distance traveled by an object. 08 m, 1/2 down the ramp it was . Make sure that the motion detector “sees” the objects rolling all the way down the ramp. Because kinetic energy is calculated from the mass of an object and its speed, the higher the ramp, the faster an object rolling or skidding down the ramp will be, assuming the mass of the object remains the same. Photogate, Ramp, Labquest, Rulers, Marble, We will construct the Ramp, and set up the photogate, and perform the experiment to get the data. Figure 1. This lab definitely accomplished what the objective was because after three trials we timed and watched our battery powered car move from one point to another. A ball will roll down a ramp leaving the end of the ramp and becoming a projectile with a horizontal initial velocity. 5gt^2 to calculate the time it took. Questions: Answer on lab report. 2. 1.

As a result, Galileo tried to decelerate its motion by replacing the falling object with a ball rolling down an inclined plane. Reaching its full speed at the end of the track. Extra: Try repeating this activity with different balls, such as a rubber ball, large metal ball bearing, Page 1 of 4 In this experiment, there are FOUR VARIABLES. After going a distance (75 cm) along the plank, the ball leaves the edge of the table and enters projectile motion. Depending on the distance of your ramp, mark intervals of 40 to 60 cm. time graph? What does the experiments and extensions that you may find interesting and challenging. " Question/Purpose: How does the color of a shirt effect the heat it absorbs? produced as the trolley rolls against the surface of the ramp. The force of gravity points straight down, but a ball rolling down a ramp doesn't go straight down, it follows the ramp. Explore forces, energy and work as you push household objects up and down a ramp. First, construct your ramp. { \Velocity of a ball rolling down a 15 incline vs. The independent variable will be the height of the ramp. 5. The front and back are indicated by where the photogate is Pre-lab None Lab Style Cookbook Experimental System A ball rolls down a curved ramp until it reaches a plateau. In his lab report, Eli discusses the outcomes of a modern Galileo experiment, exploring the relationship between gravity, velocity, and acceleration. This was because the position over time was increasing substantially. Many different versions of this type of activity exist and will pop up under a general Google search. There are different ways to investigate the acceleration of an object down a ramp. Context. and then use the slope of that graph to find acceleration since acceleration is dv/dt. In addition, take the following safety precautions: 1. There are a couple of significant differences that lead to the different grades. You can test how much friction an item will produce by heading to a playground. Then we tested a toy dump truck on the ramp. com, the pull of gravity acts more on an object rolling down a ramp inclined at a steeper angle, hence causing it to accelerate and move faster. From the ramps top we count down and release, which at the same time we start counting time and stop at the time when I hear the ball hit the floor. Set up the track to act as an inclined plane with height around 30 cm. This data, along with the mass of the cart was used to calculate the GPE of the cart at different locations. On a smart tool i am suppposed to graph velocity vs. Measure the balls velocity: To ensure the ball’s velocity was completely horizontal, we attached a flat plank at the end of the ramp. Introduction: By rolling a steel marble down a ramp and measuring its horizontal range, you can calculate the marble's launch velocity. time graphs.

A dialogue box This activity is based on the common experiment of running a marble down a ramp to do work on a cup. You will use this information to predict where the ball will land on the floor, and compare with direct measurement. The ball rolls down the ramp and then goes onto the horizontal plank. This lesson is the first in a two-part series on ramp building. 3. 2. When an object is sliding down an inclined ramp, several forces act upon it as shown on the diagram. This can be inferred because it is known that the ball takes the same amount of time to roll down each section of the ramp. At the top of the ramp, the car’s energy is in the form of gravitational potential energy (mgh). Pre Lesson: Questions 1. An example of potential energy is a stretched-out rubber band -- the farther you stretch it, the more potential energy it has. People easily intercept a ball rolling down an incline, despite its acceleration varies with the slope in a complex manner. This strobe picture will be used to make position vs. In our experiment, we did much of the same thing; however, we used a wheel and a ramp instead of a zorb and a hill, to eliminate variables with the terrain. com To compare the kinetic energy of a ball rolling down a curved ramp and a striaght ramp. This lab activity involves rolling a marble down a ramp where the students can investigate constant acceleration motion. Each of these increments were tested three times, ensuring accurate data. Tape down the top of the ramp onto the textbooks/props (if needed). Photogate 1 Ramp and Marble C-clamp Photogate 2 Figure 1 In this lab experiment, we will measure the time it takes for a marble to roll down an inclined plane. Will the potential energy be positive or negative? If energy is conserved while the ball rolls down the incline, we should be able to write PE + KE = E, where PE is the potential energy, KE is the kinetic energy and E is the constant, total 4. e. Write down an objective/purpose of this lab in your lab report. Release the cart fro the ramp while simultaneously starting the motion sensor so that the data collection is as accurate as possible. Test the set up by releasing the cart from about halfway up the ramp and make sure that it will slow down and stop before rolling off the board. The track at one end rests on the lab table and at the other end is supported by a ring stand in the sink. 22 m long and height of ramp level is 0. From the experimental data, we will then estimate the value of gravity (g). 5. The time was measured using a water clock. Clean Up (5 pts): Starting with an initial incline elevated close to 10 cm, release your cart from rest a minimum of 40 cm in front of the motion detector, allow it to roll completely down the incline recording its motion on Lab Pro. 2. 022/1. have a golf ball, use another small ball (ping pong ball, tennis ball, etc. M u r z a k u N o v e m b e r 1 1 t h , 2 0 1 1 Yadesh Prashad, Timothy Yang, Saad Saleem, Mai Wageh, Thanoja Gnanatheevam You have probably watched a ball roll off a In this experiment, you will roll a ball down a ramp and Use the following format for your lab report in Experiment 1: Coulombs Law - IIT Science.

In this experiment, the amount of time it takes for a ball to roll down a wooden board and the length of the board will be measured. Though usually associated with thunderstorms, ball lightnings are said to last considerably longer than the split-second flash of a lightning bolt, and are a distinct phenomenon from St. The distance along the ramp which the ball rolls. Place the cart on track near the bottom end stop. In this Lab, you will study the motion of a 3-wheeled cart as it rolls up and back down a plane inclined at angle to the horizontal, and you will determine the coefficient r of rolling friction by analysis of the acceleration of the cart, followed by analysis of its Before looking at rolling objects, let's look at a non-rolling object. The momentum of the steel ball will be compared by the calculations before and after. In this exercise, you will examine acceleration by measuring the time needed for an object to roll various distances down an inclined plane – much like The ball was allowed to roll a known distance down the ramp, and the time taken for the ball to move the known distance was measured. For my lab, we rolled a tennis ball down a ramp, along a flat surface, and up another shorter ramp at a less angle. It then will collide and embed within a wooden block. The time required for the ball to roll a certain distance down the ramp. Measure distance of PVC piping from floor. The other timer will always find the time the ball takes to move through its entire run from its starting point to the zero point. Measure the distance $$h$$ vertically from the bottom of the ball to the floor, using your plumb bob as a guide to a perfect vertical. The translational kinetic energy is (1) This lab seeks to confirm the conservation of linear momentum. Then push the cart up the ramp, letting it roll freely up the ramp and back down. For my lab, we rolled a tennis ball down a ramp, along a flat surface, and up another shorter ramp at a less angle. The program does the velocity calculation (in m/sec) for you; record it on the report. It will then collide with and become embedded in a wooden block. • Show the calculations needed to find the coefficient of rolling friction for the ball on the ramp.

Physics 31210 Lab 2 PROJECTILE MOTION Introduction: By rolling a steel marble down a ramp and measuring its horizontal range, you can calculate the, Rolling Ball Lab Report acceleration for a ball rolling down an incline plane. Begin data collection and release the Smart Cart down the track. Galileo showed that the motion on an inclined plane had constant acceleration, dependent only on the angle of the plane and not the mass of the rolling body. Detailed lab experiments illustrating simple machines with accompanying worksheets Slideshare uses cookies to improve functionality and performance, and to provide you with relevant advertising. L5: There is a constant acceleration along the ramp. Theta=sin^-1((0. objectives. 4. A four meter long track is available for Galileo's "diluted gravity". In order to produce a velocity that can be reproduced, a ball will be rolled down a ramp. Our potential energy decreases along side the height. Therefore, only the component of the gravitational force which points along the direction of the ball's motion can accelerate the ball. Another idea is to find a bunch of different objects and roll them down a ramp! The objects will be rotating as they roll down the ramp, so the inertia is likely to influence the outcome. Do not stand on tables and chairs. The independent variables of this experiment are the distances from which you release the ball. To confirm this velocity with an independent measurement, you can use a photogate. You MUST release the ball from the same position every time. However, the ball was moving in a straight line on a flat plate, also decelerating due to friction. 4. Fit a linear trend and include the R2 value. Acceleration will be calculated from the slope of the linearized graph and 5 compared to the accepted value of the acceleration for a ball rolling down a ramp. This is a simulation of five objects on an inclined plane. If we take the example of the opposite extreme, the track is I am in AP Physics 1 and we did a lab where we compared a disc rolling down a ramp to a hoop rolling down a ramp. OBJECTIVE The objective of this experiment is to study projectile motion. After many trials, he observed that the amount of time it took for the ball to roll down the entire length of the ramp was equal to double the amount of time it took for the same ball to only roll a quarter of the distance. A Student Researched Lab Analysis exploring the Ballistic Pendulum. that you can form a testable hypothesis for. 3. Ramp Height Lab Report 472 Words | 2 Pages.

These measurements will then be used to find the average velocity of the ball as it rolls down the board at different time intervals. Record your calculations for each angle you used in the lab. With spacers it is 0. Energy conservation tells us that the final kinetic energy (Kf = ½mv2) equals the initial potential energy (Vi = mgh). Change in height is 0. 'Physics Experiment in Projectile Motion', and hit enter. If your cart has a plunger, face the plunger from the Motion Detector. Suppose that I have some frictionless block on an inclined plane. 6 7 INTRODUCTION 8 I didn’t get a picture of this one! Our third experiment with momentum was to explore how a heavy vehicle behaves. I have a lab report, but I can not write it in a correct way. Select a distance away from the table & tape down your bullseye target. Measure the ball’s diameter d (in meters) with a vernier caliper and enter the value on your data sheet. After all the trials are completed for the six distances, find the average time it took the ball to reach the end from each point. Record this in your notebook. The ball continues rolling until it strikes a stationary ball at the very end of the ramp. 1. We will give a steel ball an initial velocity by rolling it down a ramp. Place nail at first point. When the object is left to roll or skid down the higher, more inclined ramp to the surface, this higher potential energy can be converted into correspondingly higher kinetic energy. Plot your g positions. Step 2. Another interesting experiment would be to examine the effect of the steepness of the ramp on the speed of the car. Since the plastic container had a greater amount of GPE when rolled from a higher starting ramp, this was converted to a greater amount of kinetic, or moving, energy when rolling down the ramp. Collect and record times at . We used two A bowling ball is given a push on a lab table. 2. • Open… the file Standards from the 211 Lab Files folder. Conclusion: For this lab an iron ball was rolled down a track three times, each one increasing evenly in distance. 22 m long and height of ramp level is 0. The different mass distributions cause the rolling objects to have different rotational inertia, so they roll down the incline with different accelerations. The block can only accelerate in the direction along the plane. The distance fallen (or rolled down an The ramp and level surface will be a track and a board. Apparently, however, they are poor at detecting anomalies when asked to judge artificial animations of descending motion. 8)(0. You will use two different methods for this experiment. This is due to a decrease in height as the cart travels down the ramp. time": Excellent. Wash hands with soap and water after completing the lab. 3.

Photogate, Ramp, Labquest, Rulers, Marble, We will construct the Ramp, and set up the photogate, and perform the experiment to get the data. This is because gravity is pulling the car straight down andfriction is pulling the car back up the ramp, opposite to direction ofmotion. Figure 1 OBJECTIVES • Collect distance, velocity, and acceleration data as a cart rolls up and down a ramp. Connect the motion detector to DIG 1 of LabQuest and choose "New" from the file menu. The objective of this lab is to build a ramp on a stack of two tables, roll a marble off the ramp, have it roll across the. marks on the incline. Repeat this, but now move the photogate 40 cm from the end. Enable the ball roll 10 times to receive 10 values of the last velocity. In fact, upon Position the Motion Detector so the ball rolls down the ramp and away from it. 1. Angular Momentum Toys How can an experiment be designed to measure the change in gravitational potential energy and the change in kinetic energy as an object rolls down a ramp? Predictions: Chemical energy is used by the body to lift the car 10 centimeters up onto the top of the ramp. Open the experiment file 06C_AccelerationOnAnInclinedPlane, and then power-on the Smart Cart and connect it wirelessly to your software. Because the rolling involves both linear movement down the ramp and rotation at the same time, the linear acceleration is diminished somewhat. This is what I have come up with so far In the second part of this lab, you will examine a curved ramp called a “Brachistochrone”. I have done all the calculations to determine the gravitational potential energy The height to the floor continues to get smaller as it goes down, since height is used to calculate the potential energy. He also discovered that the speed of a falling object depends only on the height from which it falls. Procedure-Set up a 5m runway with a ramp at one end that raises 20cm. 1 Kinematics, treating the ball as a point mass in free fall Galileo designed experiments to study accelerated motion using the inclined plane. This is critical. . 3. 4. Step 3. Part I: Galileo’s Inclined Plane determine the angle of the ramp. 6) Adjust the ramp to a 10-20 degree angle and practice sending the car up and down the ramp . Ball Rolling Down Inclined Plane This demonstration shows constant acceleration under the influence of gravity, reproducing Galileo’s famous experiment. In each experiment you'll set the length and height of the ramp, and we'll use that to calculate the angle the ramp makes with the floor. What is mechanical energy? 3. 1) The inclined plane’s angle could be adjusted until the time for the ball to roll to the end was long enough for even the crude time-measuring devices of his day to produce useful results. You'll need to be able to adjust the height of one end of the ramp. Measure this using a meter stick. Set the switch on the motion detector to the track position. In this experiment, you will roll a ball down a ramp and determine the ball's initial velocity with a. Then measure the vertical height of the inclined slope and record it. For my lab, we rolled a tennis ball down a ramp, along a flat surface, and up another shorter ramp at a less angle. Keep fingers and toes out of the way of moving objects. 4) The timer was started and the cart was released down the ramp so that the recording tape was pulled through the timer. 1. Make your measurements, draw a sketch in your report, and take your shot. average acceleration down the incline. The ball rolls down the ramp and then goes onto the horizontal plank. Place the Top Marble at the top of the paper towel tube ramp. I have data from 4 trials. When released, this energy causes the car to roll down the ramp. You can pick one or more of these to work on, or you can invent a new experiment on your own. During your experiment: When the object is left to roll or skid down the higher, more inclined ramp to the surface, this higher potential energy can be converted into correspondingly higher kinetic energy. Overview In this experiment, a metal ball will be released from a vertical height h on a ramp inclined at an angle θ below the horizontal so that it rolls down the ramp without sliding. We have to figure out where to place the cup for the ball to roll into. A steel ball is given an initial velocity by rolling down a steel ramp. Students are provided with materials to setup a ramp and objects of various shapes, sizes, and masses to design an experiment to test how objects rotate as they roll down a ramp. 4. The Experiment 1. This experiment uses an incline and a low-friction cart. The most important building aspect is that the ball roll off the table horizontally after coming down an incline of some sort (it shouldn’t arc upwards into the air or face downwards as it rolls off). The potential energy of the cart decreases as the cart goes down the ramp. Experiment 4 Projectile Motion Introduction We examined projectile motion by observing a ball rolling down then leaving the ramp, thus becoming a projectile with a horizontal initial velocity. . L4: This data feels accurate and correct for a ball rolling along the floor. 2. 2. This experiment is designed to reproduce a portion of Galileo's experiments. When we plugged in the data, the equation was . The horizontal space under the ramp is critical to the experiment as it helps to ensure that the vertical part of the ball velocity is zero when the ball leaves the table. 15m from the end of the track. Analysis of the graphs of this motion will answer these questions. Repeat 4 or 5 times to get an estimate of the uncertainty in the horizontal displacement. " La Salle University Lycée St. Enter the distance in meters between the photogates. E +P. This allows them to see the difference in displacement for each second the marble has traveled. Based on the data collected, m=0. When the energy is not being used it is stored in the liver or as fat on the body. L3: The ball traveling down the ramp is moving in an accelerating, downward inclined motion. Projectile Motions Lab Conducting the Lab Our lab was conducted by letting steel balls go at the top of the ramp, which basically is almost zero velocity at the top of the ramp. Once your experiment is well aligned and your calculations and measurements agree, you get to design an experiment. 8*0. 22) = 1. You will notice a clicking sound form the Motion Detector. Rolling Down a Ramp Consider a round uniform body of mass M and radius R rolling down an inclined plane of angle θ. 599 kg, g=9. Part 1: Acceleration down a ramp 1. We will give a steel ball an initial velocity by rolling it down a ramp. A mass of 500 grams (0. Set up the ramp so that it remains at a steady incline for the entirety of the trials. The results were still valid and the experiment was successful. sections of this experiment with the next experiment. This will allow "practice" runs so that timers can locate themselves near the appropriate timing mark. The height from which the ball is released on the ramp. Stop the timer when it hits the barrier at the other end of the table. Acceleration along a ramp. In this case the situation is similar to the case with no ramp, the ball gains a kinetic energy and the velocity can be computed as before. Follow all normal lab safety rules. What did this experiment demonstrate? An object´s momentum decreases with velocity. 43 J=(0. Galileo Galilee once did an experiment by rolling different weighted balls down an inclined plane and proved that objects fall at the same speed no matter what they weigh. He argued that the speed gained in rolling down a ramp of given height didn’t depend on the slope. The potential energy of the cart at the start of the ramp is: 5. [pic] Figure 1 objectives * MEASURE THE VELOCITY OF A BALL USING TWO PHOTOGATES AND By measuring the time it took the balls to roll down different lengths of the ramp and analyzing the data, Galileo was able to determine that the position of the ball at a given time was proportional to the square of the time. In the Mass in Motion lab, you rolled a ball down a ramp to see how far it moved a cup. a wheel rolling down the road. Measure the ball's In this experiment, you will use a Motion Detector to collect distance, velocity, and acceleration data for a cart rolling up and down a ramp. 03m, and all the way down the ramp was 0. At the end Rolling - four views; How a front-wheel-drive car works; Rolling - the bowling ball problem; Jumping on a merry-go-round; An accelerating cylinder; Rolling down a ramp; Harmonic Motion. 2. In this experiment you will roll a marble down a ramp to find out. Using the plumb line, location was noted that is beneath the end of the ramp. Verify that the x and y components of projectile motion are independent;. 5 kilograms) was placed on a cart weighting 99 grams (0. Then 50 cm, . Physics 207 - Lab 5 - Linear Momentum Introduction This lab seeks to confirm the conservation of linear momentum. Lab Types: You will conduct 3 different types of lab experiments in the lab room this term. 925) I'm in grade 11 physics and we were just told to create and carry out a conservation of energy lab and do a report. The following lab report comes from Eli King, a high school student at Burlington High School in Burlington, Wisconsin. At the end of the ramp, the ball leaves with a velocity v and falls freely under the effect of Procedure 1. Like Galileo, we weighed the water from each trial so as to determine the ratio of times for each length. be used to predict the velocity with which the object leaves the ramp. Before looking at rolling objects, let's look at a non-rolling object. 06 m, 3/4 of the way down the ramp it was 0. The lab experiment was about a ball rolling on a slope, I have a height of the slope, the distance, and the time in which the ball spent to reach the end of the slope. Our two variables in this lab was a battery powered car and Nick, our lab partner. You will be listing several items in this section and you will also be pasting a photo, so leave ample space before starting the next heading. You can prop it up with a few books or something similar. You can roll a ball down a ramp, and it will pick up enough speed to “loop the loop. You want a wide range of materials like a toy car, ball, book, shoe with rubber sole, a wooden block. In this experiment, the amount of time it takes for a ball to roll down a wooden board and the length of the board will be measured. Session 7 Marble Roll Experiment 3 What Happens If You Make the Ramp Longer? 35 Blackline 3 Marble Roll Experiment 3 record sheet 38 Session 8 Another Look at Averaging 39 Teacher Record Sheet Marble Roll Experiment 1 record sheet 43 Session 9 Finding Average Distances 44 Teacher Record Sheet Marble Roll Experiment 2 record sheet 49 sum of its kinetic energy and potential energy. Suppose that I have some frictionless block on an inclined plane. Since free falling is essentially equivalent to a completely vertical ramp, he assumed that a ball rolling down a ramp would speed up in the exact same way as a falling ball would. It will then collide with and become embedded in a wooden block. These measurements will then be used to find the average velocity of the ball as it rolls down the board at different time intervals. , the end of the ramp above the floor. varies with the inclination of a ramp. Put each item at the top of the slide or ramp and let it fall down on its own. 022m. Then we will upload our data to our individual Weeblys. The proof of this idea was that if a ball rolled down one ramp, its inertia would cause it to roll up an opposite ramp of equal height. The purpose of this lab is to prove the conservation of linear momentum. 8*0. This is a slow motion video of a ball released from rest on a ramp. Which one is it? (Hollow One quarter of the way down the ramp, the height of the cart was 0. books, marbles, bullseye sign), build a ramp like the one shown at right. Description, Students will create there own questions and hypotheses for a. To use a ballistic pendulum to determine the velocity of a projectile. I have done all the calculations to determine the gravitational potential energy at the start and end, and the kinetic energy in the middle. If the angle of an incline with the horizontal is small, a cart rolling down the incline moves Experiment 5 Rolling Motion "Our business is with the causes of sensible effects" I. position raw data graph we obtained what looked like a top-opening parabola. In the "Mass in Motion" lab, a ball was rolled down a ramp to see how far it moved a cup. Measure the "effective diameter" Deff of the ball. I have also calculated Experiment: Materials- stack of books, wood ramp (shelf from cabinet), masking tape, stopwatch or watch with second hand, meter stick, pen or pencil, and tennis ball. PROCEDURE. ) or simulate one with a long wooden dowel, cardboard tube, or other materials. It will slow the trolley down and produce heat and sound. 2. Though usually associated with thunderstorms, ball lightnings are said to last considerably longer than the split-second flash of a lightning bolt, and are a distinct phenomenon from St. A steel ball is given an initial velocity by rolling down a steel ramp. The motion of the our cart increased as it went down the the ramp. I have completed the lab, but my teacher wants us to come up with 5 sources of error, and solutions to those errors. As the ball rolls down the ramp, the speed increases. Launch it from the top of the ramp and begin timing it at the 0m mark. As a ball rolls down such a curve, it undergoes a variable acceleration that results in some unique behavior. 9 m/s/s = . As its velocity is increasing, the distance that it travels in each unit of time increases. Set up a demonstration of rolling three different sized marbles down an inclined plane. With spacers it is 0. 03 degrees. 799 m. Place the cart on the track near the bottom end stop. We will calculate the acceleration a com of the center of mass along the x-axis using Newton's second law for the translational and rotational motion. 5-1 can both roll and slip, depending on the frictional force available and the angle of tilt. can of chicken broth”) 4. In this experiment, the inclined plane makes work easier by allowing gravity (without any help from you) to move the marble down the ramp. An object´s mass increases velocity. at the top of the ramp. In today's lab, the potential energy is gravitational potential energy given by PE = mgy. One person should be the timer for the whole experiment to ensure more consistent measuring. Place the cart on the track near the bottom. 7. Wear sanitized safety glasses or goggles during lab setup, hands-on activity, and takedown. The momentum of the system before and after the collision will be compared. Feed t ball mill with 250 g mass of sugar of homogenous size (obtained by screening) and note the · Material · Procedure – Step by step, numbered/bullet points, on how you are conducting your experiment. Pre Lab Questions 1 In one of your experiments you will roll a marble down a ramp to provide an initial horizontal velocity Suppose you start the marble at rest vo 0 m s and it travels a distance of d down the ramp Use 1 D kinematics to predict the velocity of the ball vf at the bottom of the ramp Hint the acceleration of the ball down the ramp is 9 81 sin m s2 where is the angle of the ramp Record you answer in variables you will calculate the velocity with magnitudes when you perform the 1. there is no friction between the ball and the ramp) the ball just slides down the ramp, note that it does not turn at all, it just slides. time. here is a position scal Graphed Information. A student (timer) with a stop watch will call out the seconds, "One, two, three " while watching the stopwatch. land? Could you predict where it will land? In this experiment, you will roll a ball down a ramp and determine the ball’s velocity with a pair of Photogates. E =constant (2) 2 = + E mv mgy 2 1 (3) If the total energy is conserved, a graph of E vs. In this lab experiment, we will measure the time it takes for a marble to roll down an inclined plane. The Student Lab Report Handbook is the perfect student guide to preparing premier lab reports on a computer. Procedure. Observation experiments. In this lab we had to accomplish how to determine the constant movement of an object. 2. Measure the size of the ball with the help of venire calipers. 0 m. View Lab Report - Physics 110 Lab Report #4 from PHY 110 at Quinnipiac. 073m. His reasoning suggested that objects rolling down a ramp behaved similarly to objects in freefall so that he could understand freefall by studying ramps. Place the ball right at the end of the ramp (you may have to hold it there). heavier objects roll down an inclined plane in a shorter time than lighter objects. On the paper, draw a line that best represents the horizontal displacement of the ball while it travels through the air, xm. 3. For Dummies explains that when objects are rolling down an inclined plane such as a ramp, a component of the force of gravity causes it to accelerate downward. After going a distance (75 cm) along the plank, the ball leaves the edge of the table and enters projectile motion. 925 m, and the final height=0. The block can only accelerate in the direction along the plane. THEORY A round object placed on a tilted flat surface as shown in Fig. Since the perceptual deficiencies have been reported in studies involving a limited visual context, here we tested the hypothesis that judgments of a) Prediction: If we roll a ball and a cylinder down the inclined plane at the same time, which should get to the bottom first? Why? b) Do the experiment! c) What do you observe? d) Summarize Question 3 Object Information for rest of experiments a) Select one of your objects to use for the rest of experiment. In this lab small iron ball was rolled down from a track three times, and everytime the distance was decreasing, The first experiment was a track at 10 degrees inclination (120 cm), the second 15 (120 cm) and the third experiment was made ​​even two tracks at 10 degrees (200). But assuming no friction, it can be diagrams and calculated to be true. 12. Ball lightning is an unexplained phenomenon described as luminescent, spherical objects that vary from pea-sized to several meters in diameter. Determine the angle at which the table is tilted. Release the marble from the nail on the ramp, and let the ball roll off the table and onto the floor. The ramp is pushing the car straight up in the oppositedirection of gravity. Use this time to calculate the velocity the ball will have when it goes over the edge of the table: where v is velocity in meters per second, d is the length of the ramp in meters, and t is the time it takes for the ball to reach the end of the ramp, in seconds. As an object rolls down the incline, its gravitational potential energy is converted into both translational and rotational kinetic energy. g. Objective: The objective of this lab is to build a ramp on a stack of two tables, roll a marble off the ramp, have it roll across the table and fall into a cup placed on the ground. The lab employs versatile equipment that will allow you to do the “standard” experiment quickly and then branch out to new challenges that match your interests and expertise. 3. Put a mark on the ramp for where the ball will be released and where it will stop. 925= 5. This experiment is designed to reproduce a portion of Galileo's experiments. Experiment: For each run of the experiment, two people will be timing different things. To linearize this we squared the time which resulted in a linear Ball Rolled Down The Ramp Projectile Motion Lab. Jean-Baptiste De La Salle Senior High School Grade 12 STEM 5 ROLLING OBJECTS ACCELERATING DOWN AN INCLINED PLANE A Laboratory Report Presented to the The Faculty of the Senior High School Department La Salle University Integrated School – SHS In Partial Fulfillment of the Requirements for the subject General Physics I by Jalaisa Velasquez Kim Tomarong Jefferson However, this doesn’t seem to be a particularly good experiment – “this one feels harder to move” isn’t a very precise measurement. the graph velocity per trial and attach to your report. Experiment 1: Coulombs Law In this lab, the pith ball electroscope consists of two small balls (the pith balls) suspended by insulating The basis for the Law of Falling Bodies is that as the ball rolls down the ramp it accelerates. In all runs, make sure At the base of the ramp, the ball has both translational kinetic energy, KE = ½mv 2, and rotational kinetic energy, KE rot = ½ Iw2. It then will collide and embed within a wooden block. For this experiment, we followed these steps… Conclusion: In this lab we measured the acceleration of a rolling ball down a ramp at a specific height. Set up a ramp as shown in Figure 1 that will be our inclined plane. time": Generally, good. Lab Report. Purpose Determine how the horizontal velocity of a marble rolling down a ramp affects the motion of the marble in projectile motion. • A ball sitting on a shelf • A can rolling down a ramp • A swing moving back and forth • A car traveling at a constant speed of 15 m/s • A bird landing on a branch Which objects in the list experience an unbalanced force? Conservation of Energy Lab: In this lab you will conduct an experiment to study the principle of conservation of energy by observing how a toy car rolls down a ramp. The velocity increased uniformly and predictably from a constant acceleration. Our variables in which we used to determine speed was a little metal ball, and a metal black ramp we placed the ball on to measure its speed. Experiment 4: Rolling cart at different angles. If you give the cart a gentle push up the incline, the cart will roll upward, slow and stop, and then roll back down, speeding up. The track forces the ball to travel down along its surface and will move with an acceleration related to “g” and the angle of the track. This velocity is measured along with the horizontal and vertical distances which the projectile After that, I rolled down the first ball and amount of time it took to travel off the ramp, this was done an additional 2 the average was calculated from the last 3 rounds, this was to be repeated for so that the 2 other balls could get an These of which a measuring stable enough the balls at the they traveled this it was on the ramp, recorded The way the angle of the incline affected the ball’s velocity was tested by rolling the ball down an incline at angles of 5°, 10°, 15°, 20°, 25°, 30°, 35°, 40°, and 45°. Drop ball then release nail. ). Potential energy is the energy that is stored in an object. Who can tell me the meaning of work? 2. Therefore: {} fi f f KV Kmgh K gh Eq m n. Measure the distance (in meters) from Bottom Marble to the wall that it will eventually hit. 8 m/s^2, the initial height=0. 1 In this experiment, the cart is sliding without friction down an incline. 599*9. To explore and measure the rate of spherical objects rolling down a ramp. If you don’t have a putter, use a stick of similar length (hockey stick, yardstick, etc. PE top = Total KE base mgh = ½mv 2 + ½ Iw2 Construct model ramp on chair. His argument was based on an experiment with a pendulum and a nail, shown on page 171 of Two New Sciences. We set up the same ramp that we used for our friction experiment. We marked this ramp at each distance in which we were starting the ball from. Procedure. We measured the time of flight by simply counting the number of video frames that the ball was in the air. Mark a starting position on the ramp (use a soft pencil and erase it when you have completed the lab) so that you can repeatedly roll the ball from the same place. 3) A length of recording tape was attached to the cart and threaded through the ticker timer. ) Use this acceleration in the 2 nd kinematics equation to calculate the time it “should” take for the marble to roll 70 cm. In this experiment, we will apply the Law of Conservation of Energy to objects rolling down a ramp. Step 4. 099 kilograms). Test Lab Log All of the activities in this Toolkit, and across the other Because the rolling involves both linear movement down the ramp and rotation at the same time, the linear acceleration is diminished somewhat. When he rolled the ball down only a quarter of the incline, it would take half the time as rolling down the entire incline. Using a water clock, Galileo measured the time it took for the ball to roll a known distance down the inclined plane. Your report should be about four pages long typed, and with pictures to emphasize. During your experiment: The results show that when the ramp is higher (50cm) the car went fasterdown the slope at (3. Is there a mathematical pattern to the changes in velocity? What is the accompanying pattern to the position vs. Gather some items to be tested. If the ramps are placed close to each other, the effects of friction are minimized. An object´s mass decreases velocity. e. Estimate an uncertainty in this distance $$h$$ as well. You will examine this behavior by repeating Galileo’s experiment using a Brachistochrone. In this experiment, you will roll a ball down a ramp and determine the ball’s velocity with a pair of Photogates. Set up the computer. Support ball at the end of the ramp and adjust the height of the photogate beam to the center of ball. So, with the tallest starting ramp height, the plastic container had the the most kinetic energy. 799= 4. See full list on education. Lab 3B Physics Investigation - Analysis of Projectile Motion Using IP. As the acceleration of the object is along the direction of the ramp, the forces, or the components of the forces acting perpendicularly to the ramp must add up to zero. In doing so, they have planned and executed an investigation that demonstrates that an object rolling down an incline increases its velocity and acceleration over time The Student Lab Report Handbook is the perfect student guide to preparing premier lab reports on a computer. Recall that the moment of inertia for a solid sphere equals I = (2/5)mr 2 and that v = r w. Starting with the full length of the plane, we rolled the ball twenty times down each length, timing each trial with our water clock. Homework Statement I have a lab to do in which we have a ramp set up on a table. Then we will upload our data to our individual Weeblys. From the experimental data, we will then estimate the value of gravity (g). C. I know understand what is represented on both axes of the graph and can imagine the scenario under which these variables were taken. Write an expression for the potential energy of the rolling object in terms of x and $\sin(\theta)$. His reasoning suggested that objects rolling down a ramp behaved similarly to objects in freefall so that he could understand freefall by studying ramps. Galileo’s idea for slowing down the motion was to have a ball roll down a ramp rather than to fall vertically. A piece of carbon paper was placed over the white paper, carbon side down near the impact point. Wait about a second, then briefly push the cart up the ramp, letting it roll freely up nearly to the top, and then back down. time graph to a linearized graph for a ball which is 4 rolling down a ramp. Record your calculations for each angle you used in the lab. I have also calculated Mark a point on the ramp to roll the ball from each time. Write a hypothesis that answers the problem and is tested by the experiment. . 073m. "If the mass of a car is related to the distance the car will travel down a ramp, then the heavier the car the farther the car will travel because it has more momentum. 1m/s). 3 The purpose of this lab is to compare a distance vs. Still room for improvement. According to Education. Favorite Experiments contains all the information needed for the experiments in Novare textbooks Accelerated Studies in Physics and Chemistry , Introductory Physics , and Physics: Modeling Nature . Then, you will use your data to extrapolate to the acceleration on a vertical “ramp”; that is, the acceleration of a cart dropped in free fall. A Ball Rolling Down An Inclined Plane: Problem Lab Objective To Find The Acceleration Of The Ball Rolling Down The Incline Using Kinematic The Final Velocity Of The Ball Rolling Down The Incline Using Kinematics And Of Energy. 2 Set up the motion sensor with the car either rolling towards or away from it. • Create a graph of mass vs. 599)(9. Be sure the cup is on the Starting Circle (on the measuring strip), with the opening facing the end of the ruler, at the start of each trial. Depending on the distance of your ramp, mark intervals of 40 to 60 cm. Create a “Materials” heading in your lab report. We measured the horizontal initial velocity using the photogate and computer. Without pushing the ball, carefully release the ball so it rolls down the ramp and goes into the cup. This lab report would earn a grade: A. Analysis of the graphs of this motion will answer these questions. Our experiment proved that Galileo could have attained the accuracy which he claimed for this experiment. d) Set the switch on the Motion Detector to the track position. If we lower the slope of the second ramp, the ball will actually travel farther up the ramp, but to the same height. time and velocity vs. Screw the fourth screw up on the ramp all the way in. In this practical the acceleration of a ball rolling down a slope will be. Label also 1m, 2m, 3m, 4m, and 5m markers from the start of the ramp. Galileo determined this by having the rolling ball trigger bells as it rolled. • Draw a free body diagram for the ball rolling down the ramp. Graphs show forces, energy and work. This lab will demonstrate the principles behind projectile motion. If the ramp is perfectly smooth (i. 3) Set the incline plane for 35 degrees. This may be accomplished by translating (moving in a straight line) the photogate from the front to the back of the steel ball on the launching ramp. Galileo argued that as the angle of incline of a track is increased, the motion of a rolling ball approaches free fall, so that the motion of the ball down the track is the same type of accelerated motion as free fall. I have done all the calculations to determine the gravitational potential energy at the start and end, and the kinetic energy in the middle. Attach the ramp to the book stack using tape. 7) Describe the acceleration of the car as it a) moves up the ramp, b) stops, and moves down the ramp. 599*9. For our time vs. 430J The gravitational potential energy at the bottom of the ramp= 0. Cut the paper towel tube in half to create a track. Connecting simple harmonic motion and uniform circular motion; A ball on a spring; A ball on a spring - energy graphs; A ball on a spring - with damping (friction) Now put the ramp back in. Therefore, only the component of the gravitational force which points along the direction of the ball's motion can accelerate the ball. Before long, all of the groups are rolling the ball down the ramp, timing each run, and recording the data. Key formula: a=gsin(theta) Angle 1: Info: Ramp is 1. Repeat this process for the incline of the ramp set at 15°. 2. Place a cup at the end of the ramp where the mark is, so when the ball bearing reaches the end it will make a sound which will make it easy to stop the stopwatch. Place the golf ball on the ruler so the middle of the ball is at the 15. Start your Lab report. Ticker Tape Timer Lab: Changing Velocity Purpose: To investigate the acceleration of a car rolling down a ramp. Lab 5 Projectile Motion. We are rolling the ball down the ramp, and letting it roll of the table. An object´s momentum decreases with velocity. If we do not get the ball in the cup we fail. Set up an inclined plane as a ramp on one end of the table and the wood block at the other end. The projectile motion was lab of report that conclusion within the example of this apartment. 095m. When the ramp inclines toward the direction of the pull of gravity, an object on the ramp rolls at an acceleration that nears the full force, according to For Dummies. 4. Rolling, Torque, and Angular Momentum Rolling Motion: • A motion that is a combination of rotational and translational motion, e. Favorite Experiments contains all the information needed for the experiments in Novare textbooks Accelerated Studies in Physics and Chemistry , Introductory Principles in Physics, and the forthcoming advanced physics text Physics Ball lightning is an unexplained phenomenon described as luminescent, spherical objects that vary from pea-sized to several meters in diameter. How can I do that Experimental and theoretical results are presented showing that a ball with a high coefficient of rolling friction can roll to a stop when it rolls without slipping down an inclined plane. time should be a horizontal line. Be sure to smooth the ramp transition with the runway with a taped firm piece of paper. If the ramp is perfectly smooth (i. Using a photogate setup I am supposed to measure the time it takes the cart to travel a given distance. In this experiment, you will roll a ball down a ramp and determine the ball's velocity. ) Use this acceleration in the 2 nd kinematics equation to calculate the time it “should” take for the marble to roll 70 cm. 1. The steepness of the incline which is measured by the ratio of height to length of the ramp. What did this experiment demonstrate? (Points : 3) An object´s momentum increases with velocity. Stack the books about 3 feet from the edge of a table. In Ramps 1: Let It Roll!, students explore ramps, discuss why different ramps work better than others, and practice procedures for testing designs and recording results.
