Positive Displacement:


Displacement is considered positive when an object's final position is located at a greater distance from its initial position. In other words, the object has moved in a specific direction with respect to its starting point.

An example of positive displacement can be a car traveling from one city to another. Suppose a car starts at City A and travels 100 kilometers in the direction of City B. The displacement of the car would be +100 km, indicating that it has moved 100 km in the positive direction (towards City B) from its initial position at City A.

Negative Displacement:


Negative displacement occurs when an object's final position is located at a lesser distance from its initial position. In this case, the object has moved in the opposite direction compared to its starting point.

To illustrate negative displacement, let's consider a person who walks 50 meters west and then turns back and walks 30 meters east. The person's initial position is the starting point, and the final position is the ending point. Since the person has moved in the opposite direction from the starting point, the displacement would be -20 meters, indicating a negative value.

Zero Displacement:


Zero displacement occurs when an object returns to its initial position after undergoing some motion. In this case, there is no overall change in the object's position.

For instance, imagine a person taking a walk around a circular park. Starting at a specific point on the circular path, the person walks around the park and eventually returns to the same starting point. In this scenario, the displacement would be 0 meters since the person's final position coincides with the initial position.

It is important to note that displacement is a vector quantity, meaning it has both magnitude and direction. The positive and negative signs indicate the direction of displacement, while the numerical value represents the magnitude or distance covered.
