Answer:
The potential energy is greater when the ball is not moving, but the kinetic energy is greater when the ball is moving.
Step-by-step explanation:
In simple words, when the ball is resting it has a lot of potential energy because if you think about the ball it has a great potential to roll down the hill...when it does roll the potential energy is converted to kinetic energy which is known as energy in motion. So The potential energy is greater when the ball is not moving (it has a great potential to roll that's how I remember this), but the kinetic energy is greater when the ball is moving.
