| motion | the state in which one object’s distance from another is changing. |
| speed | the distance an object travels in one unit of time. |
| velocity | speed in a given direction. |
| acceleration | the rate at which velocity changes. |
| linear | term used to describe a relationship between variables whose graph is a straight line. |
| nonlinear | term used to describe a relationship between variables whose graph is not a straight line. |
| formula for speed | speed= distance/time |
| formula for acceleration | acceleration=change in velocity/time |
