Euclidean vector

A vector in the Cartesian plane, showing the position of a point A with coordinates (2,3).

Illustration of tangential and normal components of a vector to a surface.

In mathematics, physics, and engineering, a Euclidean vector (sometimes called a geometric or spatial vector, or—as here—simply a vector) is a geometric object that has magnitude (or length) and direction and can be added to other vectors according to vector algebra. A Euclidean vector is frequently represented by a line segment with a definite direction, or graphically as an arrow, connecting an initial point A with a terminal point B, and denoted by $\overrightarrow{AB}.$
