1. An energy posses by an object due to its motion is called kinetic energy. Example a moving bullet, blowing wind ,a rotating wheel etc.
2. An energy posses by an object due to its position is called potential energy. Example you do work while winding the key of a toy car. The energy transferred to the spring inside is stored as potential energy.
