motion and force
| Question | Answer |
|---|---|
| position | an objects location in space |
| motion | an objects change in position in a specific amount of time |
| rate | a measure, quantity, or frequency, typically one measured against some other quantity or measure |
| linear motion | objects move along lines |
| displacement | describes the distance an object moves in a specific direction. |
| scalar quantity | distance alone |
| vector quantity | a displacement |
| speed | distance per unit time |
| equation for speed | speed= distance/time distance/time= meters/second |
| instantaneous rate | information about exact points in time |
| average rate | a normal rate |
| velocity | is speed plus the direction along the path |
| uniform motion | motion that has a constant rate |
| formula for velocity | velocity = final position-initial position/ final time-initial time |
