Explanation:
Detailed explanation-1: -If an object comes back to its initial position, its displacement will be zero.
Detailed explanation-2: -Answer and Explanation: If the velocity of an object is doubled then for a particular period of time, the distance will also gets doubled.
Detailed explanation-3: -Displacement is the distance and direction of an object’s change in position from a reference point.
Detailed explanation-4: -So, if an object starts from point A and after travelling some distance it comes back to the same point A, then there is no change in position, so displacement is zero. Thus, displacement is zero, if initial and final positions are the same even though it travelled some distance.
