Potential Energy
Potential energy, abbreviated as PE, also called gravitational potential energy, is the possessed energy by a body due to its relative position in a gravitational field. As the elevation of the body decreases the less potential energy.
Potential Energy Types
- Chemical Energy - When two substances are combined or mixed together to produce a chemical reaction.
- Elastic Energy - The energy stored in objects as the result of deformation, such as a spring when stretching or compressing.
- Electric Energy - Energy stored in an electric field or transported by an electric current.
- Gravitational Potential Energy - The energy stored in an object due to its height above the earth.
- Magnetic Energy - A natural phenomenon by which some objects produce attractive or repulsive forces on other materials.
- Nuclear Energy - Energy stored in the nucleus of an atom.
