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. A fast-moving object has a high speed and covers a relatively large distance in a short amount of time.Contrast this to a slow-moving object that has a low speed; it covers a relatively small amount of distance in the same amount of time.elocity 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.
