Question

what happens to a 5 rupee coin on top a card placed on a glass when the card is flicked with a push?

Answer 1

The activity is used to understand the concept of inertia. When you flick the card, the card will move, but due to inertia of rest, the coin will tend to remain in it's original position. As the card moves away and is removed from the bottom of the coin, the coin will fall inside the glass.
