Question

When we put a card on a glass then put a coin on the top of card. Then we hit card from finger then card move but coin falls in glass Why?

Answer 1

This is because of the "inertia". Initially both the card and the coin are at rest. when the card is flicked it comes in contact into motion. The coin, however, remains at rest due to the inertia of rest. As a result, when the card is flicked, only the card flies away and the coin falls into the glass tumbler.

HOPE THIS HELPS!
