Answer:
The gravitational potential energy decreases and the kinetic energy increases. The gravitational potential energy is transformed into kinetic energy as the ball rolls down the ramp.
Step-by-step explanation:
The gravitational potential energy is the energy due to the position of a body above the ground.
Kinetic energy is the energy due to the motion of a body.
From the law of conservation of energy "energy is neither created nor destroyed but transformed from one form to another".
As the ball rolls down the ramp, the potential energy at the height is converted to kinetic energy.
