Velocity is defined as the rate of change of displacement.
i.e Velocity=Displacement / Time
It is a vector quantity and its SI unit is m/s.

Velocity is a physical vector quantity; both magnitude and direction are needed to define it. The scalar absolute value of velocity is called speed, being a coherent derived unit whose quantity is measured in the SI as metres per second or as the SI base unit of.
example, "5 metres per second" is a scalar, 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.
