Question

In which case the displacement of an obect is 0 ? Explain!

Answer 1

The displacement can be zero in many cases but mostly in cases where the particle's initial and final position is same, that is, when the particles returns to it's initial position after moving some distance.

Answer 2

Answer:

Displacement is the shortest distance covered by an object.

It is the minimum distance between the initial and the final position of the object.

It is a vector quantity.

It can be positive, negative or zero.

- It is zero when the object displaces, covers a certain distance and comes back where it started its journey from (the starting position).
