Ayushi Ayushi 6 years, 11 months ago

Velocity usually refers to calculating it instanteneously. If we say body A has a velocity v then it means it is at the moment of measuring. Average velocity is a term we use for the overall trip. It is defined as: total displacement / time taken clearly we are no longer concerned with any particular instant.

Actually velocity means instantaneous velocity i-e;velocity at an instant but average velocity means mean value of velocity
