Velocity is the rate of change of the position of an object. Mathematically it is division of displacement by time.It is a vector quantity.Its S.I. unit is m/s.

The velocity of an object is the rate of change of its position with respect to a frame of reference, and is a function of time. Velocity is equivalent to a specification of its speed and direction of motion (e.g. 60 km/h to the north).

Displacement by body in unit time interval is known as velocity. Formulaof velocity- v=displacement upon time and unit is meter per second

Velocity can be bestly defined as the special case of speed. It is defined as displacement upon time taken
