| Term | Definition |
|---|---|
| Energy | the strength and vitality required for sustained physical or mental activity. |
| Kinetic energy | energy which a body possesses by virtue of being in motion. |
| potential energy | the energy possessed by a body by virtue of its position relative to others, stresses within itself, electric charge, and other factors. |
| mechanical energy | the energy that is possessed by an object due to its motion or due to its position. |
| Electrical energy | energy related to forces on electrically charged particles and the movement of electrically charged particles |
| Electromagnetic energy | radiant energy that travels in waves at the speed of light. |
| Nuclear energy | the energy released during nuclear fission or fusion, especially when used to generate electricity. |
| Chemical energy | Energy stored in the bonds of chemical compounds. |
| Thermal energy | the energy contained within a system that is responsible for its temperature. |
| Energy transformation | the process of changing energy from one form to another. |
| Law of conservation of mass | in a closed or isolated system, matter cannot be created or destroyed. |
| Friction | the resistance that one surface or object encounters when moving over another. |
| Convection | the movement caused within a fluid by the tendency of hotter and therefore less dense material to rise, and colder, denser material to sink under the influence of gravity, which consequently results in transfer of heat. |
| Radiation | the emission of energy as electromagnetic waves or as moving subatomic particles, especially high-energy particles which cause ionization. |
| conduction | the process by which heat or electricity is directly transmitted through a substance when there is a difference of temperature or of electrical potential between adjoining regions, without movement of the material. |
