Velocity is a physical vector quantity; both magnitude and direction are needed to define it. The scalar absolute value (magnitude) of velocity is called speed, a quantity that is measured in metres per second (m/s or mâs â1) in the SI (metric) system.or example, 5 metres per second is a scalar (not a vector), whereas 5 metres per second east is a vector. If there is a change in speed, direction, or both, then the object has a changing velocity and is said to be undergoing an acceleration.
