Question

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

Answer 1

When smone is going frm 1 plc 2 another. Then agn he turns in the opposite direction nd returns back to the original place.Ex ball thrown up

Answer 2

Yes it is possible

Consider a situation in body is moving in circular path.Suppose body starts its motion
from point A. Body come back to its original
place after completing 1 complete rotation.

so. total displacement =0
• As body is back to its orignl position

but total distance = lenght of circular track

speed = distance/time
as distance is not zero so speed is NOT
zero

where. velocity=displacement/time
=0/t=0

Hence velocity is zero while speed is not zero
