What made the coin dWhat made the coin drop into the glass tumbler?rop into the glass tumbler?

Answer 1

Answer:

A momentary force acts on the card when it is flicked with fingers which causes it to move away. But the coin placed on it is bot does not share the motion at once and continues to stay at rest which is attributed to inertia of rest. Eventually, the coin falls down into the tumbler due to the gravitational pull.

When you flick the card out from under the penny, you allow gravity (an outside force) to act on it and drop it into the glass. The bottom of the glass stops the penny from falling. ... There's not enough friction from the card to take the penny with it.
