| average speed | distance traveled divided by the time it took to travel that distance |
| velocity | the speed of the object and its direction of motion |
| acceleration | how velocity changes over time |
| force | a push or pull |
| Newton's First Law of Motion | an object in motion will stay in motion unless a force acts on it |
| inertia | the tendency to resist a change in motion |
| friction | a force between two surfaces in contact that resiststhe motion of the surfaces past each other |
| Newton's Second Law of Motion | if an object is acted on by a net force, the object will move in the direction of the net force |
| Newton's Third Law of Motion | for every action there is an equal and opposite reaction |
| m/s | label for average speed |
| m/s heading east | example of velocity |
| Newtons | label for force |
