The following situations can have a displacement of zero:
- A person walks in a straight line from point A to point B and then returns back to point A.
- A car completes one full lap around a circular track and ends up at the starting position.
- A pendulum swings back and forth, returning to its original position after each swing.
- A ball is thrown directly upwards and falls back down to the initial throwing position.
- A person jogs around a circular path and completes several laps, always ending up at the starting point.
These situations involve motion that brings the object or person back to the original position, resulting in a displacement of zero.
