Have you ever wondered how things are moving??!! It’s all because of the kinetic energy. When an object is moving it has energy. Since the object is in motion it needs energy. The moving object may have rotational or horizontal or vertical movement. Energy can change its form kinetic energy to potential energy and potential energy to kinetic energy.
An example is a car being driven up a hill, during which time it is demonstrating kinetic energy or energy in motion. When it sits on the top of the hill it has potential or stored energy. If it is then allowed to roll back down the hill the potential energy changes again into kinetic energy.
