Answer 2

Yes, we can say that displacement can be +ve, -ve or 0.

$\textbf{Positive Case }$:

Displacement can be +ve in case it will don't retrace its path.

For example, if an object moves from A to B and then from B to C in straight line then displacement is from A to C in straight line.

$\textbf{Zero Case }$:

Displacement is said to be zero in case object returns to its starting position.

For example, if an object move from A to B and again from B it reaches A, then it will show the displacement zero.

$\textbf{Negative Displacement }$:

Displacement is said to be negative when the final point is opposite to the starting point.
