Question

the displacement of a moving object in a given in
terval of time is zero what the distance travelled by the object also be zero justify your answer

Answer 1

no distance will not be zero as displacement is zero because the body start from a point is coming back to that same point so displacement is zero. Distance will be more than displacement mean 0

Answer 2

No It is not true that if DISPLACEMENT is 0 So DISTANCE would be 0. DISPLACEMENT is the Shortest Distance traveled by the object and DISTANCE is the Total Distance traveled by the object. 
let us consider that there is a boy named Rahul who wish to go to a stationary shop to buy a pen and he take the path ABCD in a square such that he first travel 50 m from A to B and then travel 50 m from B to C and then travel 50m from C to D and finally travel 50m from D to A.
Here the DISPLACEMENT travelled is 0 as the boy returned to the point where he started i.e to point A.
But the DISTANCE travelled by him is 200m so it proves that WHEN DISPLACEMENT is 0 THEN DISTANCE is not always 0.
