A truck is parked at the bottom of a hill. It moves from the bottom of a hill and parks at the top. How does the truck's potential energy when it is at
the bottom of the hill compare to its potential energy when it is at the top
of the hill?

A. The truck's potential energy is lower at the top of the hill compared to when it is at the
bottom of the hill.
B. The truck's potential energy is the same at the top of the hill compared to when it is at
the bottom of the hill.
C. The truck's potential energy is greater at the top of the hill compared to when it is at
the bottom of the hill.
D. The truck's potential energy is zero at the top of the hill compared to when it is at the
bottom of the hill.
