Physics

The scenarios that illustrate the conversion of potential energy to kinetic energy is a ball rolling down a hill.

The ball at the top of the hill has gravitational potential energy because of its height above the ground. As the ball rolls down the hill, this potential energy is converted into kinetic energy. The height of the ball decreases, so the potential energy decreases, and the speed of the ball increases, so the kinetic energy increases.

Option A

A compressed spring has elastic potential energy due to its deformation. When the spring is released, the potential energy is converted into the kinetic energy of the object attached to the spring as it moves.
