| Term | Definition |
|---|---|
| acceleration | the change in velocity per unit of time |
| average speed | the theoretical constant speed at which an object would have to travel in order to go a given distance in a given period of time. |
| constant speed | speed that does not vary over time |
| deceleration | a negative change in velocity per unit of time |
| distance | how far between two objects or locations |
| force | a push or pull |
| gravity | a force of attraction between two masses |
| position | the location of an object |
| speed | the distance traveled by an object in a unit of time |
| time | how long it takes to get from one place to another |
| t | time |
| x | position "distance" |
| v | speed |
| a | acceleration |
| the triangle (delta) | change in |
| delta t | change in time |
| delta x | change in position |
| delta v | change in speed |
| Xi | initial position |
| Xf | final position |
| v= delta x/delta t | speed equals change in position divided by change in time (speed formula) |
| a= delta v/delta t | acceleration equals change in speed divided by change in time (acceleration formula) |
