Question

explain why when the card was flicked it was able to move out from underneath the coin causing it to fall into the cup. hint? question would using a penny which has less inertia than the nickel affect how difficult it would be to flick the card out from underneath it to get it into the cup? explain your answer. hint? question

Explanation:

For the first question, the card moves out from under the coin when flicked because of inertia. The coin, due to its inertia, wants to remain at rest and falls into the cup as the card is removed quickly. For the second question, a penny with less inertia than a nickel would be easier to dislodge by flicking the card. Less inertia means less resistance to a change in its state of rest, so it is more easily affected by the removal of the card.

Answer:

1. The card moves out from under the coin when flicked because the coin has inertia. Inertia is the tendency of an object to resist a change in its state of motion. The coin wants to stay at rest, so when the card is quickly removed, the coin falls into the cup due to gravity.
2. Using a penny which has less inertia than a nickel would make it easier to flick the card out from underneath it to get it into the cup. Since the penny has less inertia, it has less resistance to a change in its state of rest. So, a smaller force or quicker movement of the card is sufficient to separate the card from the penny and make the penny fall into the cup.
