Physical Science
| Term | Definition |
|---|---|
| heat | In physics, a form of energy associated with the movement of atoms and molecules in any material. |
| light | is the only form of energy that we can actually see directly. It is formed through chemical, radiation, and mechanical means |
| sound | is produced when an object vibrates. form of mechanical energy |
| electricity | energy made available by the flow of electric charge through a conductor; "they built a car that runs on electricity" |
| transformation | the process of changing one form of energy into another, such as nuclear energy into heat or solar energy into electrical energy |
| mechanical energy | is the energy that is possessed by an object due to its motion or due to its position. can be kinetic or potential |
| Law of Conservation of Energy | is a law of science that states that energy cannot be created or destroyed, but only changed from one form into another or transferred from one object to another. |
| solar | The energy the Earth receives from the sun, primarily as visible light and other forms of electromagnetic radiation. (See renewable resource.) often refers to processes that use this energy to generate heat or electricity for human use |
| wind | power obtained by harnessing the energy of the wind. |
| nuclear energy | is the energy released by a nuclear reaction, especially by fission or fusion. uses fuel made from mined and processed uranium to make steam and generate electricity. |
| biomass | is a renewable energy source from living or recently living plant and animal materials which can be used as fuel. |
| fossil fuels | A hydrocarbon deposit, such as petroleum, coal, or natural gas, derived from the accumulated remains of ancient plants and animals and used as fuel. |
| wave energy | is a renewable energy whereby we capture the energy that is being generated naturally by waves. - See more at: |
| geothermal | a form of energy obtained from within the earth, originating in its core; also, energy produced by extracting the earth's internal heat |
| tidal | energy obtained by harnessing tidal power |
| hydroelectric power | pertaining to the generation and distribution of electricity derived from the energy of falling water or any other hydraulic source. |
