Energy Stores
There are several different types of energy stores. These are...
Kinetic energy
- The energy stored by an object’s movement.
Gravitational potential energy
- The energy stored in objects raised above the Earth’s surface.
- This energy exists because of the Earth’s gravitational field.
Chemical energy
- The energy stored by chemical bonds between atoms.
Elastic energy
- The energy stored when an object is being stretched or squashed.

Nuclear energy
- The energy stored in the nucleus of an atom.
Internal energy
- Internal energy is the sum of the kinetic energies and potential energies of all the particles in an object.
Electrostatic energy
- Electrostatic energy is stored in objects due to electric charges.
- Objects with like charges repel; opposite charges attract.
- Work is done to move charges against electric forces.
