| average speed 1 | total distance an object travels divided by the total time it takes to travel that distance |
| constant speed 1 | a speed that does not vary |
| displacement 1 | distance and direction of an object's change in position from the starting point |
| distance 1 | how far an object moves |
| instantaneous speed 1 | speed of an object at a given point in time; such as that given on a speedometer |
| speed 1 | distance an object travels per unit of time |
| velocity 1 | the speed and direction of a moving object |
| acceleration 2 | rate of change of velocity; can be calculated by dividing the change in the velocity by the time it takes the change to occur |
| balanced forces 3 | forces on an object that combine to give a zero net force and do not change the motion of the object |
| force 3 | a push or pull exerted on an object |
| inertia 3 | resistance of an object to any change in its motion. If motionless, an object remains still; if moving it keeps moving unless a net force acts on it. |
| net force 3 | sum of the forces that are acting on an object |
