If a stone rests at the top of a hill, it has potential energy due to its position or height above the ground.
Potential energy is a type of energy that is stored in an object or system as a result of its position or configuration. In this case, the stone has gravitational potential energy because it is at a higher altitude and has the potential to fall due to gravity. The amount of potential energy an object has depends on its mass, the acceleration due to gravity, and the height or position above a reference point.
As the stone rolls down the hill, its potential energy is converted into kinetic energy, which is the energy of motion. The stone’s speed increases as it moves down the hill, and its kinetic energy increases accordingly. At the bottom of the hill, the stone will have its maximum kinetic energy and minimal potential energy.
