Explain with an example that the magnitude of displacement may be zero

1.	Explain with an example that the magnitude of displacement may be zero but the corresponding path length is not zero.
Answer» <P> Solution : For EXAMPLE, if the CAR starts from O, GOES to P and then returns to O. The final POSITION coincides with the initial position and the displacement is zero. However, the path length of this journey is OP + PO = 360 m + 360 m = 720 m. Thus, the magnitude of displacement for a course of motion may be zero but the corresponding path length is not zero.
