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 |
Newton | The SI unit used for force (N). |
Net Force | All forces acting on an object at one time. |
