Velocity is mainly a vector expression of the displacement that an object or particle undergoes with respect to time . The standard unit of velocity magnitude (also known as speed ) is the meter per second (m/s). Velocity can be expressed either as an average over a period of time, or as an instantaneous value at a single moment in time
the mathematical formulae is : Displacement/time

Velocity is a vector quantity, and average velocity can be defined as the displacement divided by the time.
