Energy
Term | Definition |
---|---|
Energy | The ability to do work or cause a change. |
Kinetic energy | Energy that an object has due to its motion. |
Potential energy | The energy an object has because of its position; also the internal stored energy of an object, such as energy stored in chemical bonds. |
Gravitational potential energy | Potential energy that depends on the height of an object. |
Elastic potential energy | The energy of stretched or compressed objects. |
Mechanical energy | Kinetic or potential energy associated with the motion or position of an object. |
Nuclear energy | The potential energy stored in the nucleus of an atom. |
Thermal energy | The total kinetic and potential energy of all the particles of an object. |
Electrical energy | The energy of electric charges. |
Electromagnetic energy | The energy of light and other forms of radiation, which travels through space as waves. |
Chemical energy | A form of potential energy that is stored in chemical bonds between atoms. |
Energy transformation | A change from one form of energy to another; also called an energy conversion. |
Law of conservation of energy | The rule that in the absence of outside forces the total momentum of objects that interact does not change. |
