| motion | the change in an object's position |
| force | a push or pull that acts on an object |
| inertia | the tendency of an object at rest to remain at rest or an object in motion to remain in motion |
| speed | measure of the distance an object travels in a given amount of time |
| velocity | measure of both speed and direction |
| acceleration | change in an object's velocity |
| newton | force required to accelerate a mass of 1 kg at 1 m/sec |
| gravity | force that causes objects with mass to be attracted, or pulled toward one another |
| friction | a force that resists motion of one surface across another surface |
| a pass receiver in football would apply this to stop the ball | force |
| Newton's first law of motion | an object at rest will remain at rest unless a force acts on it |
| distance traveled divided by the time it took to travel that distance equals this | average speed |
| If you are driving north and make a turn and are now driving east, what has changed? | velocity |
