Answer:
Force of gravity!
Explanation:
The reason I say this is because a "dependant varible" is a variable that is being measured in a science experiment. Even though potential energy could be the answer it isn't because in this experiment the kinetic and potential energy are being measured. Depending on the height of the ball on the ramp the force of gravity will depict whether it goes faster and longer.
Hope This Helps :)
