| acceleration | the rate at which velocity changes over time: an object accelerates if its speed, direction, or both change |
| instantaneous speed | the rate of motion at a particular instant in time |
| reference point | a location to which another location is compared |
| velocity | the speed of an object in a particular direction |
| average speed | the total distance traveled divided by the total time taken |
| motion | an objects change in position relative to a reference point |
| speed | a measure of how fast something moves |
| displacement | the change in position of an object |
| position | the location of an object |
