Cultural definitions for vector
In physics and mathematics, any quantity with both a magnitude and a direction. For example, velocity is a vector because it describes both how fast something is moving and in what direction it is moving. Because velocity is a vector, other quantities in which velocity is a factor, such as acceleration and momentum, are vectors also.
