If someone was to reproduce this exact experiment, what would they need to know? Be sure your procedure is in past tense (use the passive voice). Be sure the procedure you create is safe. Observations: Record the following information as you perform the experiment: . The vertical distance from the top of the ramp to the floor (in metres); . The mass of your object (in kilograms); . The length of the ramp (in metres); . The time it takes for the object to roll down the entire length of the ramp (in seconds); . You may wish to collect this piece of data several times to later determine an average time. Analysis: 1. Calculate the gravitational potential energy the object has when it is at the top of the ramp. 2. Determine the average time the object takes to roll down the ramp. 3. Determine the average speed of the object as it rolled down the ramp (HINT: you know both the distance the object rolled, as well as how long it took, on average). 4. Double your average speed in order to determine the final speed of the object at the bottom of the ramp. This can be done because: Vit uf Uang = 2 2( varg ) = vitusAnalysis: 1.

Double your average speed in order to determine the final speed of the object at the bottom of the ramp. This can be done because: vituf 2 2( vang) = vit us ...and " is zero (assuming you started the object from rest). 5. Determine the kinetic energy the object has at the bottom of the ramp. 6. Compare the kinetic energy of the object at the bottom of the ramp to the gravitational potential energy of the object at the top of the ramp. This is known as the efficiency: Ex(atthebottom) x 100% Eg(atthetopo) 7. Was the conservation of energy principle upheld? If not, why do you think this is? Conclusion: In one or two sentences at most, summarize your findings.Lab: Conservation of Energy In this task, we will verify the conservation of energy principle. You will do this by rolling an object down a ramp, and compare its energy at the top of the ramp to its energy at the bottom of the ramp. It is up to you to choose which object you use (make sure they can roll, like a ball, a soup can, or a toy car), the height from which you start it rolling down the ramp, and how you will measure the time it takes for the object to roll the entire length of the ramp. For this investigation, you will be prompted for most parts, and even given some of the wording. In this task, anything in italics must be answered or completed; anything in regular type can be copied directly. Check with your teacher if you have any questions. Read through the lab instructions below, and develop a procedure. Once your teacher has approved your procedure, complete the inquiry, and submit the required parts below. Purpose: The purpose of this lab is to... What is the purpose of this investigation? What are we trying to prove? Hypothesis: How do you think the energy at the top of the ramp will compare with the energy at the bottom of the ramp? Why do you think this? Materials: Read through the observations and analysis sections to determine what materials you might need. Make a complete list of all the materials you use to collect your data. Procedure: Read through the observations and analysis sections to determine what information you will need to collect, and then write a procedure for the investigation. Don't forget to include how the timing was accomplished, and how certain variables (such as height, starting time, etc.) were controlled
