In Exercises 3.13 and 3.14, we have carefully distinguished between average speed and magnitude of average velocity. No such distinction is necessary when we consider instantaneous speed and magnitude of velocity. The instantaneous speed is always equal to the magnitude of instantaneous velocity. Why?

Q. When a particle moves with variable velocity, which of the following relations are false?
(I) Average speed = average velocity
(II) Instantaneous speed = instantaneous velocity
(III) Distance covered = magnitude of displacement
