Inertia

What is Inertia?

Inertia is Newton's first law which states that an object at rest will stay at rest and an object in motion will stay in motion. Inertia can also be described as the resistance an object has to a chance in its state of motion or rest.

Inertia is commonly and simply defined as,a body in motion stays in motion, a body at rest stays at rest.

Materials & Procedure

Materials: 1 balloon& 1 penny, 8 quarters and credit card, 1 cup, an index card and 1 dime, newton's beads.

Procedure:

-Penny in a balloon.

*Before blowing air into the balloon put penny into balloon.

*Tie the balloon once its blown to a decent size (Not too over blown)

*Hold the balloon from the top (where it's tied) and start spinning it.

*You will notice the penny moving even after you stop spinning the balloon.

-Quarters & Credit card.

*Place 5-6 quarters (as as many as you'd like) vertically

*By using a credit card try knocking out one quarter at a time!

*You'll notice that the only quarter that moves is the one the card is acting on!

(It works, I promise-It's Inertia!)

-Cup& Card:

*Place an index card on top of a card & a quarter on top of the index card.

*Flick the index card

*You'll notice that the quarter stays at rest while only the index card is in motion.

-Newton's Beads:

*Place Newton's beads at the edge of a table

*Pull out beads and watch them continue to come out.

Scientific Principle:

Inertia is everywhere you look!for example, everyday you drive in a car with a smooth ride. One day when you press the brakes on the car too late you'll notice that your body moves forward even though the car is stopped. Why does this happen? Inertia! Your body was still in motion even though the car wasn't.

Safety Regulation : All regular safety regulations apply to this project!
