How does the gravitational potential energy of the four books compare?
A. The books have the same gravitational potential energy.
B. The gravitational potential energy increases from top to bottom.
C. The gravitational potential energy decreases from top to bottom.
D. The books are not moving so they do not have gravitational potential energy.

B. It is converted to kinetic energy.
C. It is destroyed as the ball moves.
D. It is used to make the ball slow down.
