Potential energy is energy that is stored in an object. Potential energy can transfer into other forms of energy like kinetic energy. Kinetic energy is energy an object has because of its motion.
A ball held in the air, for example, has gravitational potential energy. If released, as the ball moves faster and faster toward the ground, the force of gravity will transfer the potential energy to kinetic energy. The higher the ball, the more gravitational potential energy -- it will fall longer and faster as it accelerates toward the earth
Potential energy is the energy that an object has at the starting height and kinetic energy is the energy it has released
