| Energy = | the ability to do work or cause change |
| Kinetic energy = | the energy of motion |
| Potential energy = | energy that is stored and held in readiness |
| Elastic potential energy = | energy associated with objects that can be stretched or compressed |
| Gravitational potential energy = | energy that depends on height and gravity |
| Mechanical energy = | energy associated with the motion or position of an object (GPE and KE) |
| Thermal energy = | the total energy (KE and PE) of the particles INSIDE a substance or material |
| Chemical energy = | potential energy stored in chemical bonds that hold chemical compounds together |
| Electrical energy = | the energy of moving electric charges |
| Electromagnetic energy = | the energy of light and other forms of radiation |
| Nuclear energy = | the potential energy stored in the nucleus of an atom |
| Nuclear fission = | nuclear reaction that occurs when the nucleus SPLITS (nuclear power plants) |
| Nuclear fusion = | nuclear reaction that occurs when nuclei fuse or join together (Sun) |
| Energy transformation = | the process of changing one form of energy to another |
| Law of conservation of energy = | states that energy cannot be created or destroyed |
| Joule = | amount of work you do when you exert a force of 1 newton to move an object a distance of 1 meter |
| Work = | Force x Distance |
| Heat = | a form of energy that travels from warm to cold areas |
| Temperature = | A measure of the average kinetic energy in a substance |
