Complete the statement. Assume that Anthony's mass did not change.
The gravitational potential energy stored between Anthony and Earth () as he hiked toward the summit.

 - increased
 - decreased
 - stayed the same
Think about how the distance between Anthony and the center of Earth changed.
The summit of the mountain was higher than the point where Anthony started hiking. As he hiked toward the summit, the distance between Anthony and the center of Earth increased. So, the gravitational potential energy stored between Anthony and Earth increased as he hiked toward the summit.
