Vocabulary Study Tool for Vocab Science Quiz (physics vocabulary II [27])
| Term | Definition |
|---|---|
| energy | the strength and vitality required for sustained physical or mental activity |
| potential energy | the energy possessed by a body by virtue of its position relative to others, stresses within itself, electric charge, and other factors. |
| elastic potential energy | potential energy that is stored when a body is deformed |
| kinetic energy | energy that a body possesses by virtue of being in motion |
| gravitational potential energy | Gravitational energy is the potential energy associated with the gravitational field. |
| mechanical energy | energy in a mechanical form |
| thermal energy | Thermal energy is the part of the total potential energy and kinetic energy of an object or sample of matter that results in the system temperature. |
| electrical energy | energy made available by the flow of electric charge through a conductor |
| chemical energy | that part of the energy in a substance that can be released by a chemical reaction |
| nuclear energy | the energy released during nuclear fission or fusion, esp. when used to generate electricity. |
| electromagnetic energy | Radiant energy is the energy of electromagnetic waves |
| energy transformation | Energy transformation or energy conversion is the process of changing one form of energy to another. |
| law of conservation of energy | the fundamental principle of physics that the total energy of an isolated system is constant despite internal changes |
| temperature | the degree or intensity of heat present in a substance or object |
| absolute zero | the lowest temperature that is theoretically possible, at which the motion of particles that constitutes heat would be minimal |
| 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 |
| convection | he 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 |
| radition | the emission of energy as electromagnetic waves or as moving subatomic particles |
| conductor | a person who directs the performance of an orchestra or choir |
| insulator | a thing or substance used for insulation |
| melting | make or become liquefied by heat |
| freezing | the freezing point of water. |
| evaporation | the process of becoming a vapor |
| boiling | the action of bringing a liquid to the temperature at which it bubbles and turns to vapor. |
| condensation | water that collects as droplets on a cold surface when humid air is in contact with it. |
| thermal expansion | Thermal expansion is the tendency of matter to change in volume in response to a change in temperature |
| law of universal gravition | inverse square law |
