Another name for stored energy is potential energy. Objects are able to store energy as a result of their position. For example, the ball of a demolition machine stores energy when it is raised to a vertical position.
Potential energy exists as either gravitational potential energy or elastic potential energy. Gravitational potential energy refers to energy that is stored in an object as a result of vertical positioning. Elastic potential energy is energy stored in elastic materials as a result of stretching or compressing. Both forms of potential energy are determined by their relation to an arbitrary point known as the zero position.
