The ball rolling down an incline has its maximum potential energy at
A)the top.
B)a quarter of the way down.
C)halfway down.
D)the bottom.

Question

Quizplus · Accepted Answer

The maximum potential energy of a ball on an incline is at the top because that is where the height is the greatest and height is directly proportional to potential energy. As the ball rolls down the incline, its potential energy decreases and its kinetic energy increases until it reaches the bottom where its potential energy is at a minimum and its kinetic energy is at a maximum.
