| Momentum | |
| Mass | The amount of matter in an object |
| Speed | the distance an object moves a certain period of time |
| Velocity | measure of both the speed and direction of a moving object |
| Inertia | resistance of an object to change in it's state of motion |
| Relative Motion | change in position of one |
| Balanced Force | equal forces acting in opposite directions |
| Force | A push or a pull |
| Weight | a measure of the pull of gravity on an object's mass |
| Instantaneous speed | the speed at any given point |
| Acceleration | Change in velocity during a particular time period |
| Friction | force between surfaces that resists the movement of one surface past the other surface |
| Frame Reference | object an observer uses to detect motion |
| Gravity | the force of attraction that exits between any two objects |
| Newton | metric system, the unit used to measure force or weight |
| Speedometer | that shows instantaneous speed |
| Law | describes events or relationships that exist in nature |
| Air-resistance | the friction from air molecules hitting an object moves through the air |
| Net force | combination of all the forces acting on an object |
