Take a piece of thread. Tie a small piece of stone to one end of the thread. Hold the other end of the thread in hand and whirl it round. Note the motion of the stone. If the thread breakes suddenly, the stone files off along tangent to the circle at the instant.
Read the above passage and answer the following question:
(i) which force is whirling the stone ? who is providing this force ?
(ii) why does the stone fly off along the tangnet to the circle at that instant?
(iii) what value of life do you learn from this?

Explanation

(i) The force whirling the stone is the centripetal force acting on the stone. This force is being provided by our hand whirling the stone.
(ii) when the thread breakes, centripetal force is no longer provided. Therefore, inertia of direction takes the stone along the straight line path , which is along tangnet to the circle at the instant.
(iii) Form these observation,we learn that to keep our children on track ,motivational has to be continous.the applies equally to our lives too. the moment our efforts and motivation cease, our life/children are likely to go off the track.
