| position | where something is located, is always described using a reference point (The boy is in front of the door) |
| distance | a measure of how far something travels along a path that might change |
| average speed | how far something goes in a certian amount of time (distance divided by time) |
| instantaneous speed | the speed that something is going at an exact moment |
| displacement | how far something is from where it started |
| acceleration | an increase or decrease in speed (rate of change of velocity) |
| relative velocity | motion that depends on your frame of reference or what you are comparing your motion to |
| motion | the change in position over time |
| reference | used to tell the positon of something |
| speed | how fast something is going |
| average velocity | the measure of motion that tells how fast an object moved over a specific displacement (total displacement divided by time) |
| average acceleration | the change in velocity divided by the time interval during which the change occurred |
