As the ball is rolling up a hill, its potential energy is increasing while its kinetic energy is decreasing.
Potential energy is the energy an object possesses due to its position or condition. When the ball is rolling up the hill, it gains potential energy because it's moving against gravity and getting higher above the ground. As it moves upward, its potential energy increases.
Kinetic energy, on the other hand, is the energy of motion. When the ball is rolling up the hill, it's moving against the force of gravity and slowing down due to the incline. As its speed decreases, its kinetic energy also decreases because kinetic energy is proportional to the square of the velocity.
In summary, as the ball rolls up the hill, its potential energy increases as it gains height, and its kinetic energy decreases as it loses speed.
I hope this helped!
