Mathematicians and scientists call a quantity which depends on direction a vector quantity. A quantity which does not depend on direction is called a scalar quantity.

RFC 1 - Host Software ... A scalar is a quantity that can be defined by a number alone. A vector, on the other hand, must be specified by both a number and a direction. From a geometric point of view, a vector can be defined as a line segment having a specific direction and a specific length.

The remainder of this lesson will focus on several examples of vector and scalar quantities (distance, displacement, speed, velocity, and acceleration). As you proceed through the lesson, give careful attention to the vector and scalar nature of each quantity.
