=Definition - Stored energy that comes from position=

=Facts about potential energy=
 * 1) Potential energy has two forms (gravitational potential energy, Elastic potential energy).
 * 2) To calculate potential energy you must know the mass and height.
 * 3) Objects that have potential energy do not use their energy until they move.
 * 4) Potential energy can become any other form of energy.
 * 5) Anything with height and does not move has potential energy.

=Examples of potential energy= = = =Review=
 * A marble on a table
 * A book on a shelf
 * A bowling ball on a hill

Chemical potential energy vs. Gravitational potential energy Chemical potential energy is energy in its chemical bonds and gravitional potential energy is an object being held above the earths surface.

=Units=

=Formula=

Pe= Wh
Pe- potential energy W- weight h- height
