yeah displacement can be positive or zero
when an object is moving straight until some distance then it is positive if the initial point and final point of a moving object is same then it is zero
when an object is moving straight until some distance then it is positive if the initial point and final point of a moving object is same then it is zero

POSITIVE DISPLACEMENT:
As long as the object is moving along a straight line or takes curves in the direction that we have taken +ve according to our convention, displacement will be +ve.
Eg. A car moving along a straight road
(Δx is a positive value)
NEGATIVE DISPLACEMENT:
When Δx comes out to be negative, then the displacement is negative. Here, the object travels in the opposite direction to our +ve convention.
Eg. A car moving in reverse direction.
ZERO DISPLACEMENT:
When Δx comes out to be zero, Δx = x₀ - x' = 0, then we have zero displacement, i.e no horizontal change in position.
Eg. A person goes from A to B ad returns to A, his displacement is zero (Δx = 0)
**x → horizontal position
Δx → change in horizontal position
x₀ → final position
x' → initial position
Hope this helps. :)
