In mathematics, physics, and engineering, a Euclidean vector (sometimes called a geometric or spatial vector, orâas hereâsimply a vector) is a geometric object that has magnitude (or length) and direction. Vectors 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 A B â . {\displaystyle {\overrightarrow {AB}}.}.
