A 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 occurs at the top of the incline because at that point, the ball has the highest elevation and therefore the most gravitational potential energy. As the ball rolls down the incline, its potential energy is converted into kinetic energy until it reaches the bottom, where its potential energy is at its minimum.
