As you know, the displacement is the shortest distance between two points ; the initial point and the final point. The displacement is independent of the path followed by the object and this itself is the beauty of the concept of displacement. We may take different paths to reach a destination, and the length of the path may be different, but all the paths result in the same displacement.
