Question

(a) A body in motion can have zero velocity but not zero speed. Justify by giving an example.​

Answer 1

Answer:

Average velocity = Net displacement/time taken

Average speed = Total distance/time taken

Net displacement can be zero but total distance cannot be zero.

So, average velocity can be zero but average speed cannot be zero.

hope it helps.

for example if a body moves from a point A to B and back to A it covers some dist. but the displacement remains 0 due to initial and final point being the same..similarly, we cn say that it have some speed but its velocity will be zero because displacement is also zero.

hope it helps..
