Types of energy store
There are many stores of energyThe capacity for doing work., including:
- magnetic
- internal (thermal)
- chemical
- kinetic
- electrostatic
- elastic potential
- gravitational potential
- nuclear

Examples of energy stores
| Energy store | Description | Examples |
| Magnetic | The energy stored when repelling poles have been pushed closer together or when attracting poles have been pulled further apart. | Fridge magnets, compasses, maglev trains which use magnetic levitation. |
| Internal (thermal) | The total kinetic and potential energy of the particles in an object, in most cases this is the vibrations - also known as the kinetic energy - of particles. In hotter objects, the particles have more internal energy and vibrate faster. | Human bodies, hot coffees, stoves or hobs. Ice particles vibrate slower, but still have energy. |
| Chemical | The energy stored in chemical bonds, such as those between molecules. | Foods, muscles, electrical cells. |
| Kinetic | The energy of a moving object. | Runners, buses, comets. |
| Electrostatic | The energy stored when repelling charges have been moved closer together or when attracting charges have been pulled further apart. | Thunderclouds, Van De Graaff generators. |
| Elastic potential | The energy stored when an object is stretched or squashed. | Drawn catapults, compressed springs, inflated balloons. |
| Gravitational potential | The energy of an object at height. | Aeroplanes, kites, mugs on a table. |
| Nuclear | The energy stored in the nucleus of an atom. | Uranium nuclear power, nuclear reactors. |
