| energy | the ability to do work or cause change |
| potential energy | energy that is stored and held in rediness |
| kinetic energy | energy that an object has due to its motion |
| chemical energy | potential energy that is stored in chemical bonds |
| thermal energy | the total energy of the particles in a substance or material |
| wave | a disturbance that transfers energy from place to place |
| longitudinal | a wave that moves the medium parallel to the direction in which the wave travels |
| transverse | a wave that moves in a direction perpendicular to the direction in which the wave travels |
| crest | the highest part of a transverse wave |
| trough | the lowest part of a transverse wave |
| wavelength | the distance between two corresponding (same) parts of a wave |
| amplitude | the maximum distance the particles of a medium move away from their rest positions as a wave passes through a medium (height) |
| reflection | the bouncing back of a wave when it hits a surfae through which it can not pass |
| transmission | when a wave travels through a material |
| absorption | a wave that is stored; not transmitted or reflected |
| refraction | the bending of waves as they enter a different medium |
| EM spectrum | the range of electromagnetic waves placed in a certain order |
| conservation of energy | energy can not be created or destroyed; it just changes form |
