Kinetic energy is one of several types of energy that an object can possess. Potential energy can be converted into kinetic energy and vice versa, but the change is always accompanied by the dissipation of some energy as heat.

Potential energy may be converted into energy of motion, called kinetic energy, and in turn to other forms such as electric energy. When electric energy is in demand, it is then released from high, PE transforms to motional (kinetic) energy and then electrical energy. If an object is moving, then it possesses kinetic energy.
