Question

why the coin drop in the glass when we flick the cardboard over the glass​

Answer 1

Answer:

Explanation:

The coin has inertia, meaning it really wants to stay in one place. ... If you flick it quickly, the coin stays in one place and then drops into the cup. An object at rest will remain at rest.

Answer 2

Answer:

The coin is kept on the cardboard, which is over a glass.

The cardboard as well as the coin are in state of rest. When we suddenly flick the cardboard, it comes to motion but the coin doesnt changes its state due to inertia.

Inertia is a property or tendency of every object to resist any change in its state of rest or of motion.

So, the coin falls into the glass.
