Students conduct an experiment using a toy car with the mass of 10g, a toy car with the mass of 20g, and a toy car with the mass of 30g. The students want to test the cars on a ramp and measure how far the cars traveled. Evaluate the information and determine the question they are trying to test with this experiment.

• Does the mass of the object influence the amount of potential energy?

• Does the amount of incline determine how far the car will travel?

• Does the mass of the car influence the amount of kinetic energy?

• Does the height of the ramp influence the amount of potential energy?
