Vectors

A vector is a quantity that has both magnitude (size) and direction. Unlike a regular number, which only indicates how much, a vector tells you how much and where to. Examples include velocity (speed and direction of movement) or force (push or pull). Vectors can be represented visually as arrows: the length shows magnitude, and the arrow points in the direction. They are used in physics, engineering, and computer graphics to model and analyze movement, forces, and other directional data efficiently and accurately.
