प्रश्न
Why does a coin, placed on a card, drop into the tumbler when the card is rapidly flicked with a finger?

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