Diffen âº Science âº Physics. Speed is the rate of change of motion, i.e. distance moved by an object in a specified time irrespective of direction. Velocity is speed with respect to direction. Speed is a scalar quantity while velocity is a vector.nstantaneous speed is the speed at any given instant of time. Average speed is the average of all instantaneous speeds or distance per time ratio. Velocity is the rate at which an object changes its position. It is a vector quantity.
