NEWTON’S THREE LAWS OF MOTION

Physics

WHY SHOULD WE LISTEN TO THIS OLD, DEAD WHITE

GUY???

His work has revolutionized and helped establish modern science for OVER 200 YEARS!

So what?

Without his work in mathematics and science we would not be able to understand, and enjoy, watching a small metal ball spin for two minutes in a glass.

And Physics students wouldn’t come up with such awesome rap songs about Newton’s Three Laws of Motion!

NEWTON’S FIRST LAW

An object in motion tends to stay in motion unless acted upon by an opposite force.

What is the term for this concept?• INERTIA!

NO W HOW W OU LD THIS LO O K IN REAL L IFE?

Remember, kids, don’t try this at home! (Unless an adult says it’s okay…with supervision!)

NEWTON’S SECOND LAW

When a force is put against an object it will accelerate.

HOWEVER, the more mass an object has the more force will be needed to move that object.

So if you were to serve a volleyball over a net it would not take much force. But what if you were to serve a large, round rock over that net?

• It wouldn’t go as far.• And that would really hurt!

F = ma • Force equals mass times acceleration

MAKING CONNECTIONS!

Newton’s Second law IN SPAAAACE! And on Earth.• Force, Mass and Acceleration

NEWTON’S THIRD LAW

For every action there is an equal and opposite reaction

If we blow up a balloon and then release it in midair, what is going to happen to that balloon? What about the air?

• The balloon will go flying off behind a desk, or land on someone’s head.

• The air is escaping in the opposite direction, propelling that balloon to land on someone’s head.

• Like so!

THE THIRD LAW IN MOTION

Two almost equal masses pushing against each other

NOW WHAT?Now that you’ve taken a look into the wondrous world of Newton’s Three Laws of Motion…and observed some examples…it is time for you to create your own!

With a partner, brainstorm and design a model to demonstrate one of Newton’s Three Laws of Motion.

Using the materials provided for you (or with permission to bring in materials from home) create the model for your designated motion.

After careful and meticulous experimentations, present the model to the class with your partner. (Remember, it is okay and encouraged to ask for volunteers for your demonstrations. Just like Ansley!)
