An object that starts and ends at the same point would have zero displacements.
<h3>What is displacement?</h3>
Displacement is the property of a body or an object to be moved from one place to another.
Thus a body that moves or is moved from point A to point B has been displaced.
A body with zero displacements either did not move at all or finished at the same point it started.
For example, a body that moves from point A to B, and then back to A will have zero displacements.
