| a force is a | push or pull |
| every forces has | size and direction |
| newton's first law | an object in motion stays in motion... |
| newton's second law | f=ma |
| newton's third law | action/reaction |
| inertia | an object's resistance to change |
| gravity | the force that pulls objects with mass together |
| friction | a force that opposes motion |
| to find net force: if the forces are in opposite directions | subtract |
| to find net force: if the forces are in the same direction | add |
| the metric unit for force | newton |
| balanced forces | Create NO change in motion |
| unbalanced forces | creates a change in motion |
