| Instantaneous Speed | The rate of which an object is moving at that point in time |
| Velocity | Speed of an object in a given direction |
| Slope | the "steepness" of the line |
| Acceleration | the rate at which velocity changes, increasing/decreasing speed, or change in direction. |
| Force | A push or pull |

| Net Force | All forces acting on an object at one time. |
| Unbalanced Forces | Can cause an object to start, stop, or change direction |
