Word Origin for vector
"quantity having magnitude and direction," 1704, from Latin vector "one who carries or conveys, carrier," from past participle stem of vehere "carry, convey" (see vehicle).
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.
