Question

The displacement of a moving object in a given interval of time is zero would the distance travelled by the object also be zero give reason

Answer 1

no,it cannot be zero.
for example: if a body moves from point A to B which covers 3km and again it moves back to point A.it mean that the distance= 3+3=6km and displacement =3-3=0km
so, by this example u can understand that distance travelled by an object cannot be zero.
