Write down a hypothesis and observational experiment to test one of Newton’s laws of motion. Explain your reasoning please!

Penny on a Card Experiment to test the law of inertia. An object at rest remains at rest unless and external force acts on it.

Materials for the Penny on the Card Experiment:

• a small plastic cup,
• a playing card
• a coin.

Procedure:

• Put a playing card on top of the plastic cup
• Put a coin on top of the card
• With a sharp flick, hit the card out from under the coin! Or pull it really quickly toward you.
• The coin will drop into the cup.

Explanation:

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. An object at rest will remain at rest.
