Question

an object has moved through a distance. Can it have zero displacement? if yes, then please answer with an example

Answer 1

yes an object moved through a distance can have 0 displacement.
this can happen in the case if an object after moving through a distance comes back to its original position.
for example boy moves 2 km from point A moves to a point B and returns back to point A. then the distance moved will be 4 km but the displacement will be zero .

Answer 2

If the object moves in a circular path completing revolutions as integral multiples of distance,then it has zero displacement as it reaches its starting point but some distance is covered in that process.
