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 |
