| Term | Definition |
|---|---|
| energy | the ability to do work |
| kinetic energy | energy which a body possesses by virtue of being in motion |
| potential energy | he 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 | power derived from the utilization of physical or chemical resources, especially to provide light and heat or to work machines |
| Chemical energy | Energy stored in the bonds of chemical compounds |
| Thermal energy | to the energy contained within a system that is responsible for its temperature |
| Energy transformation | processes that convert energy from one type |
| Law of conservation of mass | discovery that mass is neither created nor destroyed in chemical reactions |
| 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 |
