| Term | Definition |
|---|---|
| Motion | a change in position over a period of time |
| Speed = | distance/time |
| reference point | location to which you can compare OTHER locations (it is --- far from the reference point) |
| velocity | vector which has both speed AND direction |
| acceleration | RATE that speed changes (speeding up OR slowing down) |
| Acceleration = | change in speed /time |
| centripetal acceleration | acceleration in a circular motion |
