Complete the statement. Assume that the motorcycle's mass did not change.
The gravitational potential energy stored between the motorcycle and Earth () as Lamar rode up the hill.

 - decreased
 - increased
 - stayed the same
Think about how the distance between the motorcycle and the center of Earth changed.
The top of the hill is higher than the bottom of the hill. As Lamar rode toward the top of the hill, the distance between the motorcycle and the center of Earth increased. So, the gravitational potential energy stored between the motorcycle and Earth increased as Lamar rode up the hill.
