| motion | an object’s change in position relative to a reference point |
| acceleration | the rate at which velocity changes over time |
| speed | the distance traveled by an object divided by the time |
| velocity | the speed of an object in a particular direction |
| force | push or pull |
| displacement | the change in position of an object (must be a straight line and include direction) |
| net force | The sum of all the forces acting on an object |
| reference point | nonmoving point from which motion is measured |
| distance | total length of the path traveled between two positions. (can be a straight line but it doesn’t have to be) |
