demonstrate the relationship between velocity & acceleration
| Term | Definition |
|---|---|
| force | a push/pull exerted on an object in order to change the motion of the object- force has size & direction |
| motion | an object's change in position relative to a reference point |
| reference point | a stationary object that is used to describe an object's motion |
| speed | the traveled divided by the time interval during which the motion occurred |
| velocity | the speed of an object in a particular directiom |
| acceleration | the rate at which velocity changes over time- an object accelerates if its speed, direction, or both change |
