WebDec 4, 2015 · 1 Answer. Yes indeed. Derivative of velocity with respect to time is acceleration.That means if accelerations is zero, velocity must be constant. Now that constant could be anything like it could be 5 m/s .Also if the velocity is 0 (which is itself a constant) also indicates that acceleration is zero. Awesome!
