Difference between instantaneous speed and instantaneous velocity.

1.	Difference between instantaneous speed and instantaneous velocity.
Answer» (a) Instantaneous velocity is always tangential to the path followed by the particle. (b) A particle may have constant instantaneous speed but variable instantaneous velocity. (c) The magnitude of instantaneous velocity is equal to the instantaneous speed. (d) If a particle is moving with constant velocity then its average velocity and instantaneous velocity are always equal. (e) If displacement is given as a function of time, then time derivative of displacement will give velocity.
