Dear student 
The velocity of an object is usually defined as the rate of displacement that a particle or an object undergoes within a span of time. Velocity is stated to be a physical vector quantity meaning both direction and magnitude have to be taken into consideration in order to define it.The SI unit of velocity is meter per second (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 an object's speed and direction of motion (e.g. 60 km/h to the north).
