| Chemical energy | Energy stored in an object when it is above the ground. The greater the height, the more gravitational potential energy an object has. |
| Elastic potential energy | Energy stored in a stretched or squashed spring. Stretched rubber bands also store elastic potential energy, which is released when they are let go. |
| Nuclear energy | Energy stored inside the small particles that make up all matter. Nuclear energy is released in a nuclear power plant, in a nuclear bomb explosion, and inside the Sun. Nuclear reactions produce heat and light. |
