Vector (physics/math)
A one-dimensional array of numbers that can be used to represent a point in a multidimensional space. Commonly in 3-space a vector is viewed as a number (a magnitude) plus a direction (compare with scalar). A vector can be represented by an arrow whose length represents the magnitude and the direction represents the direction. For example, velocity is a vector; velocity tells you how fast something is traveling, and its direction.
