| chemical potential energy | energy stored in chemical bonds. |
| elastic potential energy | energy stored when an object is compressed or stretched. |
| energy | the ability to do work and cause a change to occur. |
| 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. |
| joule | SI unit of energy. |
| kinetic energy | energy a moving object has because of its motion; depends on the mass and speed of the object. |
| law of conservation of energy | states that energy can never be created or destroyed. |
| mechanical energy | sum of the potential energy and kinetic energy in a system. |
| potential energy | stored energy an object has due to its position. |
