| Term | Definition |
|---|---|
| Kinetic energy | energy a moving object has because of its motion; depends on the mass and speed of the object. |
| joule | SI init of energy. |
| Potential energy | stored energy an object has due to its position. |
| 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 above earth's surface and the object's mass. |
| mechanical energy | the total amount of potential and kinetic energy in a system and can expressed by this equation. |
| The law of conservation of energy | states that energy cannot be created of destroyed. |
