Question

Give one example of a situation in which a body has a sudden average speed but its average velocity is zero

Answer 1

Hey mate

Your question's explanation can be given by taking a simple example...

Let's say a body moves 10m right and then 10m left (comes back to original position) in let's say 10 seconds

So AVG speed will be = total distance/total time
which will be 10+10/10 = 2m/s

but AVG velocity = total displacement/total time

look carefully displacement is zero...as body has come back to its original position...means final position - initial position = 0

so AVG velocity will be ZERO

Hope you understand

Thanks
