Velocity as a Vector Quantity. Velocity is a vector quantity that refers to the rate at which an object changes its position.. Imagine a person moving rapidly-one step forward and one step back-always returning to the original starting position.While this might result in a frenzy of activity, it would result in a zero velocity.ust as distance and displacement have distinctly different meanings (despite their similarities), so do speed and velocity. Speed is a scalar quantity that refers to how fast an object is moving.. Speed can be thought of as the rate at which an object covers distance.
