| acceleration | Rate of change of velocity. |
| average speed | Total distance an object travels divided by the total time it takes to travel that distance. |
| balanced forces | Forces on an object that combine to give a zero net force and do not change the motion of the object. |
| 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. |
| force | A push or pull exerted on an object. |
| Law of Conservation of momentum | States that the total momentum of objects that collide with each other is the same before and after the collision. |
