Question

an object has moved through a distance can it have zero displacement.justify your answer with an example

Answer 1

Yes it can become zero, when the object will again come back on the same position eg :
A body is on point A and it covers a distance and it reaches B and if that body will again come back to the point A , then we can say displacement is zero .

Answer 2

no,if the object moves from A to B it covers a certain distance. therefor,displacement is not zero
AND
yes,if the object come on its place back i.e. object moves from A to B and again come back to A then displacement is zero


because displacement is the smallest distace
