Question

give an example when average velocity is zero but instantaneous velocity is never zero.

Answer 1

I think that it would be possible if a body or particle moves in a circle

AS,,

while moving in a circle the displacement at a point comes zero.
And velocity =displacement/time.

But during the path that the body covers (distance) it never comes to rest but keeps moving and changing direction in order to come back to the same point. This way the velocity is never 0. Even when it is changing its direction, even at that instant the instantaneous velocity is not 0.

Hope this is ur required answer
