| chemical potential energy | a type of energy that is stored in bonds between atoms and transformed into kinetic energy when the bonds are broken |
| elastic potential energy | a type of energy that is stored in an object made of elastic material when force has been used to change the object's shape |
| electrical energy | the flow of electrons among atoms in a substance that conducts electricity |
| energy | the ability to generate a force that does work |
| gravitational potential energy | energy that is stored in an object because of its position |
| joule | the unit of work and energy |
| kinetic energy | energy that arises from an object's motion |
| mechanical energy | energy that can move objects through contact; the sum of potential and kinetic energies in a system |
| nonrenewable resource | a resource that humans use more quickly than nature can replace, such as coal, natural gas, or oil |
| nuclear potential energy | a type of energy that is stored in an atom's nucleus and that is transformed into kinetic energy when a nucleus breaks apart or another nucleus is added to it |
| renewable resource | a resource that is replaced through natural cycles, such as solar, wind, and hydroelectric power |
