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?

• A. No,because if the moving object comes back to its initial position the distance travelled is not zero.
• B. Yes, displacement and distance are equal. So both are zero.
• C. Yes, because displacement is always greater than distance travelled.
• D. None of the above

Answer 1

The correct option is A No,because if the moving object comes back to its initial position the distance travelled is not zero.

Though the moving object comes back to its initial position the distance travelled is not zero.
Displacement is calculated on the basis of initial and final position. If initial and final position are same, displacement is zero. But distance is the total distance covered from initial to final position. So, it cannot be zero in this case.
