| Centripetal | Type of force that keeps objects moving in a circle |
| Acceleration | Any change in velocity |
| Gravity | the attraction between two objects (and is dependent upon mass) |
| Reference Point | used to tell if something is moving |
| instantaneous speed | spped at any given instant |
| average speed | total distance divided by total time traveled |
| speed | the rate of motion |
| velocity | speed and direction |
| momentum | mass x speed |
| inertia | tendency of an object to resist a change in motion |
| Unit for acceleration | m/s/s |
| Unit for speed | m/s |
| Rate of falling objects | 9.8 m/s/s |
| Terminal Velocity | The point at which a falling object stops accelerating; when air resistance and gravity are balanced |
| Air resistance | The force opposite of gravity that slows objects falling through air |
| How fast an object is going if it had been falling for 5 seconds | 49 m/s/s |
| Projectile | anything shot or thrown though the air |
| Example of Newtons 1st law | Connors books do not leave his locker unless he takes them out |
| Example of Newtons 2nd law | bowling ball is harder to stop than a tennis ball traveling at the same speed |
| Example of Newtons 3rd law | jumping on a trampoline |
