Hello friend
Yes the average velocity of a moving body can be zero
Velocity is displacement/time
Displacement is the shortest length between the initial and the final positions
When the body returns back to its initial position then displacement becomes 0 and even velocity.
For example when you run in a circular path. You return to the initial position after a while, making he displacement 0. Hence velocity also becomes 0.
Hope it helps

yami3:
just take an example of a bus like u r sitting on a window seat , the person sitting next to u will observe u as in a
rest position
but with respect to an individual standing outside u r in motion
Yes
hence rest and motion are relative terms
Yes.....it can be an example
I've told the answer in a simple way
rest and motion are relative means that rest or motion is defined by how the observer perceive the event from his frame of reference.for eg. right now you might be sitting or standing or anyhow be in the state of rest whereas an alien in the outer space might be seeing you moving since you are moving along with the rotation of earth according to his frame of reference.
another common example given in most textbooks is suppose you are in a moving train,but with respect to the passenger next to you,you are in rest whereas a man standing outside the train may see you moving along with the train.Hope this helps
A good example

yes AVG velocity of a body can be zero when a body displacement is zero as velocity is equal to displacement /time for ex running on a circular path and come back again at the same place ....
