| Balenced force | Occur when the total of all fources on an object equals zero and the object does not move. |
| unbalanced forces | Occur when the net force on an object does not equal zero; results in the object changeing motion |
| Newtons 1st law of motion | An object at rest will stay at rest and an object in motion will stay in motion unless acted on by an unbalanced force. |
| Newtons 2nd law of motion | force= mass x acceleration |
| Newtons 3rd law of motion | For every action, there will be an equal and opposite reaction |
