Average Velocity

Average Velocity

Average velocity is defined as the ratio of total displacement of the object to the total time taken. It is expressed as: 

large Average; Velocity (v_{AB}) = frac{Total; Displacement }{Total ;time ;taken}

Average Velocity (vAB) = [Initial Velocity (u) + Final Velocity (v)] / 2
