Terms | Definitions |
|---|---|
 speed | the distance traveled divided by the time (s=d/t) |
| average speed | the total distance traveled divided by the total time taken |
| instantaneous speed | the speed of an object at one moment in time |
| acceleration | change in velocity divided by time taken for the change to take place |
| positive acceleration | speed up |
| negative acceleration | slow down |
| velocity | speed and direction of a moving object |
| inertia | tendency of an object to resist a change in it's motion |
| momentum | a measure of how hard it is to stop a moving object; dependent on it's mass and velocity |
| law of conservation of momentum | the total momentum of objects that collide with each other is the same before and after the collision |
| collision | when two or more objects hit each other |
| motion | a change in position |
| relative motion | a change in position of one object compared to the position of another |
| distance | how far an object moves |
| displacement | the distance and direction an object moves relative to it's starting point |
