| reference point | A reference point is a fixed, stationary object or location used as a baseline to measure or compare the position, movement, or direction of other objects |
| position | an object distance and reference point |
| motion | motion is the process of changing position |
| acceleration | is a measure of the change in velocity during a period of time |
| newtons second law | states that the acceleration of an object equals the net force on the object divided by the objects mass. |
| friction | is a force that resists the sliding motion of two surfaces that are touching . |
| free body diagram | is a simple model to understand systems of subjects with an amount of applied forces |
| contact force | is a push or a pull on one object by another object that's touching it. |
| net force | is the sum of all the forces acting on an object |
