Distance is the total movement of an object without any regard to direction. We can define distance as to how much ground an object has covered despite its starting or ending point.

Let’s understand the concept of distance with the help of the following diagram:

How is Displacement defined?

Displacement is defined as the change in position of an object. It is a vector quantity and has a direction and magnitude. It is represented as an arrow that points from the starting position to the final position. For example- If an object moves from A position to B, then the object’s position changes. This change in position of an object is known as Displacement.

Displacement is represented as an arrow. Which of these symbols is probably displacement?

The complete length of the path between any two points is called distance. Displacement is the direct length between any two points when measured along the minimum path between them.

In other words, distance is the total length of path an object has moved. Displacement is just simply the shortest path from start to finish. Notice how in the image below the red line is the distance or complete path take, while the blue line is the shortest path from the girl starts and finishes in her journey.
