Examples of Potential Energy
Potential energy is stored energy from an object. Instead of coming from motion, it can come from its position relative to others, internal stress, electric charge, or its condition. This object has the capability of producing energy as these conditions change. This energy could be mechanical energy, chemical energy, electric energy, nuclear energy, or magnetic energy.

Mechanical Potential Energy
Mechanical energy is the energy of movement. All items have potential energy based on their position (gravitational potential energy) and ability to bounce (elastic potential energy). When the potential energy of an object is combined with its kinetic energy, it results in mechanical energy.
Examples of Gravitational Potential Energy
When something has a high position, its gravitational potential energy is high. For example, a book on a high bookshelf has a higher gravitational potential energy than a book on the bottom shelf because it has farther to fall. Other examples of items with gravitational potential energy include:
A raised weight
Water that is behind a dam
A car that is parked at the top of a hill
A snow pack (potential avalanche)
A yoyo before it is released
River water at the top of a waterfall
A book on a table before it falls
A child at the top of a slide
Ripe fruit before it falls
