Examples of energy stores
Examples of energy types
| 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. |
| Heat energy (or Internal energy) | 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. |
| Electrical or 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 or strain energy | The energy stored when an object is stretched or squashed. | Drawn catapults, compressed springs, inflated balloons. |
| Sound | Sound is caused by a vibrating object. The vibrations pass to surrounding particles of matter and then from one particle to another in waves. Sound energy moves through solids, liquids and gases as these all have particles to pass on the vibrations. | Music playing through earbuds, a plucked guitar string, someone talking. |
| Gravitational potential | The energy of an object at height. | Aeroplanes, kites, mugs on a table. |
