1.	Tie a small piece of stone to one end of a string and whirl it in a circle with your hand The centripetal force required by the stone is being supplied by your hand through the string If the string breaks suddenly you observe that the stone flies off along the tangent to the circle at that instant . Read the above passage and answer the following questions: (i) Why does the stone fly off along the tangent to the circle at the instant the string breaks (ii) What lessons of life do you learn from this study ?
Answer» (i) At the instant the string breaks the centripetal force is no longer provided to the stone Therefore the stone is not being forced to move along the circle On account of inertia of direction the stone flies off along the tangent to the circle that intant. (ii) To change the straight line path of stone to circular path a continous force (= centripetal) is needed The moment this force ceases the stone reverts to its natural st line path The same is true in day to life Continuous motivation and efforts are needed to keep the young kids on the desired path The moment we stop motivating kids may revert to the path of their choice .
