A vector is a mathematical object that has both a magnitude (size) and direction.
You can use them to represent the velocity and acceleration of a moving object, so vectors are very important in physics, engineering and mechanics. Vectors are commonly represented as line segments in two- or three-dimensional space or, more abstractly, as columns of numbers.
