Question

Purpose: Determine the kinetic energy of a constant velocity car when it is switched on.

A. Design an experimental procedure to find the kinetic energy of a constant velocity car. Make a list of the equipment you would use.

B. Describe the overall procedure you would follow. Provide enough detail so another student could replicate the experiment, including any steps necessary to reduce experimental uncertainty.

C. Clearly list what data you need to collect.

D. List what equations you need to use with the data you collected to find the kinetic energy of the car.

E. Describe the energy conversion that occurs while the constant velocity car is running. What other types of energy does the car have, aside from kinetic energy?

F. If you were to actually complete this lab, what are some potential sources of error that could cause your answer to be incorrect?

Answer 1

The kinetic energy is proportional to the square of the speed, so doubling the speed increases the kinetic energy by a factor of 4.
