| Elastic Potential Energy | energy stored when an object is compressed or stretched |
| Chemical potential energy | energy stored in chemical bonds |
| Gravitational potential energy | energy stored by objects due to their position above Earth's surface; depends on the distance about Earth's surface and the object's mass |
