| Linear motion | Motion that moves place to place without repeating. |
| Harmonic motion | Motion in a repeated sequence, called a cycle. |
| Oscillator | A system that shows harmonic motion. |
| Period | Time for one complete cycle; measured in seconds. |
| Frequency | Number of cycles per second; measured in hertz. |
| Amplitude | How big a cycle is in terms of distance or angle away from at rest position; measured in meters or degrees. |
| Damping | A gradual loss of energy due to friction and gravity. |
| Equlibrium point | Place halfway up y-axis on position vs. time graph; at rest position. |
| Phase | "Where" oscillator is in its cycle. |
