EXPLAIN THE FOLLOWING:


1-When a smooth card placed over the mouth of a tumbler is flicked sharply in the horizontal direction , the card flies away , but the coin kept over the card falls into the tumbler, why?


Ans-The reason is that when the card is flicked , a momentary force acts on the card, so it moves away. But the coin kept on it does not share the motion at once and it remain at its place due to inertia of rest . The coin then falls down into the tumbler due to the pull of gravity.
