Final answer:
The ball has the least amount of potential energy just before it hits the ground.
Step-by-step explanation:
When a ball is dropped from a certain height, it falls to the ground due to gravity.
At the maximum height, the ball has the highest amount of potential energy because it has the greatest distance from the ground. As the ball falls towards the ground, its potential energy decreases. Just before it hits the ground, the ball has the least amount of potential energy because it is closest to the ground.
Therefore, the ball has the least amount of potential energy just before it hits the ground.
