| Term | Definition |
|---|---|
| amplitude | how much a wave is displaced from its rest position |
| electromagnetic | a wave that does not require a medium |
| transverse | a wave that displaces the medium across the wave’s direction |
| wavelength | the distance from a point of the wave to the same point |
| period | the amount of time for the wave to repeat one cycle |
| longitudinal | a wave that displaces the medium in the direction of motion |
| frequency | the number of times a wave repeats in one second |
| mechanical | a wave that requires a medium in order to move |
| scalar | a quantity that has size but not direction |
| potential energy | energy that is waiting to be used |
| displacement | how far away an object has moved |
| radiation | heat that is transferred across a distance |
| vector | a quantity that has size and direction |
| conduction | heat that is transferred by direct contact |
| kinetic energy | energy that is in use |
| convection | heat that is transferred by moving air or water |
| inertia | an object’s resistance to change |
| wave | a repeating disturbance than transfers energy |
| gravity | the attractive force between two objects |
| velocity | the speed and direction of an object |
| force | any push or pull |
