Vector

Vector

A quantity, drawn as an arrow, with both direction and magnitude. For example, force and velocity are vectors. If a quantity has magnitude but not direction, it is called a scalar. Temperature, length, and mass are examples of scalars.

 

Arrow vector on coordinate axes; labels show "magnitude = length" along arrow, "argument = angle" at its angle from horizontal.
