Question

Can displacement be zero even wheen distance is not zero??

Answer 1

Question:
Can displacement be zero even wheen distance is not zero??

Answer :-
Yes
Displacement can be zero even when distance is not zero
For example : In a simple harmonic circular motion a particle moving in a circular path will at any instant return to its initial position after completing the circle ,when it returns the displacement covered is as it returns to its initial position but the distance covered is not zero it is the total circumference of the circle.

This statement can be true in one condition and that is when the Starting point and the Finishing point of a moving object coincide or falls on the same then the displacement is definitely zero but distance travelled will be considered as though it moves from its original place but do not find its shortest distance.

A condition when distance is not zero but displacement is zero is that when we throw a stone upwards in the air it does not displaces and hence considered as the zero displacement. Here the distance travelled will be the height till the stone reaches upwards and come down to rest.
