| Chemical energy | energy stored in the bonds of atoms and molecules of substances (e.g., food, biomass, petroleum, natural gas, and propane contain stored chemical energy) |
| Elastic energy | stored in objects by force (e.g., stretched rubber band or balloon) |
| electrical energy | movement of electrons (e.g., electrons moving through wires is electricity; lightning) |
| energy | the ability to cause change or do work |
| Energy Conservation | management of the use of energy resources |
| Energy Resources | natural resources that can be used as a source of energy to do work |
| Energy transformation | process of energy changing from one form to another |
| Kinetic energy | energy of motion |
| Law of Conservation of Energy | states that energy is neither created or destroyed; it only changes form |
| Light energy | energy from light waves (e.g., solar, light bulb) |
| Mechanical energy | movement of objects or substances from one place to another |
| Nonrenewable | natural resources that cannot be replaced once depleted (e.g., oil, coal, natural gas, nuclear) |
| Potential energy | stored energy of an object because of its position or shape |
| Radiation | the transfer of energy from a light source (e.g., Sun, fire, light bulb, burner) to an object or substance |
| Renewable | natural resources that can be replaced by nature (e.g., solar, hydropower, wind, biomass) |
| Sound energy | movement of waves through a substance or object caused by vibrations |
| Thermal energy | a form of kinetic energy resulting from the motion of particles that is transferred as heat; associated with the temperature of substances |
| Transform | changing from one form to another (e.g., energy transformation) |
