Question

Give one example if asituation in which a body has a certain average speed but its average velocity is zero

Answer 1

Answer:

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

Answer 2

Answer:

Motion of a boy from his home to shop (in one direction) and back to home (in its reverse direction) is an example of a situation in which a body has a certain average speed but its average velocity is zero.
