Positive and negative displacements refer to the direction of motion or movement of an object relative to a reference point.
Positive displacement occurs when an object moves in the same direction as the reference point. For example, if a person walks 5 meters forward from a starting point, their displacement would be positive (+5 meters) because they moved in the same direction as the reference point.
On the other hand, negative displacement occurs when an object moves in the opposite direction to the reference point. Using the previous example, if the person walks 3 meters backward from the starting point, their displacement would be negative (-3 meters) because they moved in the opposite direction to the reference point.
In summary, positive displacement describes motion in the same direction as the reference point, while negative displacement describes motion in the opposite direction. It is important to note that the terms positive and negative are relative to the chosen reference point and do not necessarily indicate good or bad outcomes.

Positive displacement:
- Walking forward from your house to the grocery store.
- Driving in a straight line on a highway.
- Climbing up a flight of stairs.
- Swimming across a pool from one end to the other.
- Running in a marathon and crossing the finish line.
Negative displacement:
- Walking backward to retrace your steps.
- Driving in reverse to park your car.
- Descending a flight of stairs.
- Swimming back to the starting point after reaching the other end of a pool.
- Moving in the opposite direction during a race or competition.
