When a body starts from rest or it changes its direction of motion, it is called initial velocity. Considering initial velocity is equal to zero (u = 0), only when the object starts from rest. Generally, at the time (t = 0), the initial velocity is zero. Yes, you can have zero velocity and medium velocity that is not zero. Each time when a circular motion is there in a body the movement is zero as well as its speed. An object with zero velocity has zero velocity only if it maintains a zero speed (or resting state) for a certain time. If not, it is faster.
