| acceleration | a word or measurement used to describe how quickly something changes speed or direction. |
| kinetic energy | energy of motion |
| potential energy | energy stored to be released at a later time |
| force | any push or pull |
| centripetal force | a force which pulls an object into a curved path |
| motion | a change in position over time |
| velocity | speed in a certain direction |
| inertia | the tendency for an object to move in a straight line at a constant speed |
| Newton's First Law of Motion | The law of inertia |
| Newton's Second Law of Motion | Force = mass x acceleration |
| Newton's Third Law of Motion | the action - reaction law |
| friction | a force that opposes motion when two or more objects rub together |
| momentum | Momentum = mass x velocity |
| Law of Conservation of Energy | Energy cannot be created or destroyed, it can only change from one form to another |
| speed | describes how quickly an object moves |
| physics | the study of motion |
| work | work is force over a certain distance |
