Definition of Displacement

Displacement is a vector quantity representing the shortest directed straight-line distance from the initial position to the final position of an object.

$\text{Displacement} = \text{Final} \text{Position} − \text{Initial Position}$

Condition for Zero Value

If an object travels along any path (e.g., circular track or round trip) and returns to its starting point, its initial and final positions coincide, making displacement zero ($s = 0$).

When the initial and final position of the object is the same
