| acceleration | Rate of change of velocity. |
| average speed | Total distance an object travels divided by the total time it takes to travel that distance. |
| distance | How far an object moves. |
| displacement | Distance and direction o an object's change in position from the starting point. |
| velocity | The speed and direction of a moving object. |
| inertia | Resistance of an object to a change in its motion. |
| instantaneous speed | Speed of an object at a given point in time. |
| net force | Sum of the forces that are acting on an object. |
| speed | Distance an object travels per unit of time. |
| formula for speed | speed= distance/time |
| formula for acceleration | acceleration=change in velocity/time |
| Units to express speed | m/h or m/s or km/min |
| Units to express acceleration | m/s2 or m/s/s |
