In a locker room, a softball was sitting in the middle of a level bench. Simon bumped the bench and the softball rolled toward the edge. Then, the softball fell off the bench, hit the ground, and rolled quickly along the flat floor of the locker room. Simon tried to grab the ball, but he could not reach it before it rolled underneath some lockers.

When was the most gravitational potential energy stored between the softball and Earth? Assume that the softball's mass did not change.

• when the ball was sitting in the middle of the bench

• when the ball was about to hit the locker room floor

• when the ball was rolling quickly towards the lockers

A blue jay was sleeping in its nest near the top of a pine tree. The blue jay woke up and needed to eat, so it flew to the ground to look for food. When the blue jay landed on the ground, it saw that there was no food around. Then, the blue jay looked up and saw a bird feeder on a low branch of a nearby pine tree. The blue jay flew to the bird feeder and perched on it to eat.

When was the least gravitational potential energy stored between the blue jay and Earth? Assume that the blue jay's mass did not change.

• when the blue jay was asleep in its nest

• when the blue jay landed on the ground

• when the blue jay perched on the bird feeder
