What happen when slowly pulled the cardboard?

What happen when slowly pulled the cardboard?

Answer: When I slowly pulled the cardboard, the coin placed on top of the cardboard remained at rest but was dragged along with cardboard. Explanation: That is because, the coin was dragged by the force in the surface of the cardboard called friction.

What happens to the Matchbox case as you pulled the cardboard abruptly to the side?

Answer. It makes fire. Explanation: When you pull anything in the side of the matchbox it causes fire because of friction.

What is relationship between inertia and mass?

The tendency of an object to resist changes in its state of motion varies with mass. Mass is that quantity that is solely dependent upon the inertia of an object. The more inertia that an object has, the more mass that it has. A more massive object has a greater tendency to resist changes in its state of motion.

What happened to the coin when you flicked the index card cardboard How would you relate this to law of inertia?

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.

Does a penny have more inertia than a card?

Give the index card a firm flick. Kids may expect the pennies to fly off with the index card. However, they actually stay in the same place because of inertia. They are objects at rest staying at rest!

Why would you want to do the above tablecloth trick with heavy dishes instead of paper plates?

Place the practice cups, plates, and utensils on the tablecloth close to the edge of the cloth on the table (for practice). This makes for less tablecloth to pull out from under the stuff sitting on it. It builds your confidence.

Is friction present between a glass of water and the table?

The glass of water has inertia — it will not move unless a big enough force acts on it. The force in this activity pulling on the glass of water is the friction between the tablecloth and the glass.
