An object has kinetic energy when itâs in motion. The amount of kinetic energy an object has depends on its mass and speed. Potential energy, on the other hand, is a stored energy when an object is at rest. It describes how much work the object could do if set into motion. Itâs an energy we can generally control. When an object is set into motion, its potential energy transforms into kinetic energy.
