Scalars and Vectors

A scalar is a quantity that has magnitude and no direction. It is a one dimensional measurement of a quantity, like temperature, speed, or mass.
A vector has more than one number associated with it. It has a magnitude, called speed, as well as a direction, like North or Southwest or 10 degrees west of North. A simple example is velocity.
