Q 1. An object has moved through a distance. Can it have zero displacement? If yes, support your answer with an example.
Yes, an object having moved through a distance can have zero displacement.
If an object moves and returns to the original position, the displacement will be zero. Consider the movement in a circular path. A man walks from point A in a circular path in a park and comes back to the point A.
The distance travelled is equal to the circumference of the circular path, but displacement is zero.
