SCALAR QUANTITY

Definition

 

 

* A quantity consisting of magnitude only, not direction

Term

VELOCITY

 

 

VELOCITY

VELOCITY

 

 

VECTOR QUANTITY

Definition

 

 

* A quantity consisting of magnitude and direction

Term

VELOCITY

 

 

DISPLACEMENT

Definition

 

* A vector quantity describing the length and direction in a straight line from the position to the final position

 

(To calculate average velocity, displacement is used instead of distance travelled. The direction of the displacement becomes the direction of the calculated average velocity)

Term

VELOCITY

 

 

POSITION

Definition

 

* A vector quantity describing the location of a point relative to a reference point

 

(Previously, you determined average speed by graphing distance versus time. Similarly, you an determine average velocity by graphing position versus time)
