Complete the statement. Assume that the penny's mass did not change.
The gravitational potential energy stored between the penny and Earth () as the penny fell toward the bottom of the well.

 - decreased
 - stayed the same
 - increased
Think about how the distance between the penny and the center of Earth changed.
The bottom of the well is lower than the point where Sofia dropped the penny. As it fell toward the bottom of the well, the distance between the penny and the center of Earth decreased. So, the gravitational potential energy stored between the penny and Earth decreased as the penny fell toward the bottom of the well.
