| Term | Definition |
|---|---|
| gravity | the force between 2 objects |
| friction | the force between 2 resisting surfaces |
| static friction | the force acting on an object not moving |
| sliding friction | the force acting on an object sliding |
| rolling friction | the force acting on an object rolling over a surface |
| fluid friction | the force of an object going through a liquid or gas |
| weight | a downward force due to mass because of gravity |
| normal force | the upward force that helps support the weight |
| force | the push or pull acting on an object |
| "N" stands for | Newton |
| free-body diagram | Drawing of force |
| net force | all the forces put together |
| terminal velocity | the resistance of a falling object |
| Newton's first law | an object at rest stays at rest |
| Newton's second law | force=mass*acceleration |
| Newton's third law | every action has and equal and opposite reaction |
| mass | kg |
| momentum | kgm/s |
| velocity | m/s |
| force | N |
