Suppose a body moves from one point to another. If we draw a straight line between these two points, the length of this line is the displacement of the body no matters how much ground the body covers to reach the final point. It must be noted here that this straight line marks the shortest path between the two points. Thus, displacement can be defined as vector quantity which is the length of the shortest path connecting the point where a body starts to move and the point where the body finally reaches.
