what will happen to the coin you quickly pull the card?​

Sagot :

Answer:

The coin has inertia, meaning it really wants to stay in one place. If you move the card slowly, it isn't fast enough to overcome that force. If you flick it quickly, the coin stays in one place and then drops into the cup.

Explanation:

Explain to students that the quarter dropped into the cup when the card slid out from underneath it. This is because the quarter has inertia. The index card was set in motion, but the quarter was at rest. Since there was no force acting on the quarter, it stayed at rest and dropped into the cup.
