1. NEWTON’S 3rd LAW

2. Let’s Experiment With Chairs
2 Students, Facing One Another in the Chair
Hands outstreched like giving double high five
On three, push into the other person
What did we observe?

3. Newton’s 3rd Law describes the 1st law in more detail
Physics is all about CAUSE and EFFECT
Newton’s 3rd Law is ALL ABOUT CAUSE AND EFFECT

5. Again, Newton’s 3rd Law is about CAUSE AND EFFECT
OR.... ACTION AND REACTION

6. Newton states, correctly, that all forces occur in pairs!
For every force applied, there is an equal and opposite (direction) force applied!

7. Let’s Experiment with Newton’s 3rd Law
......With Balloons
2 Courageous Volunteers will validate Newton’s findings

8. Some 3rd Law Practice Draw the following situation
What’s the ACTION - REACTION pair here?
ACTION: Girl pushing on wall
-REACTION: Wall pushing on girl
WILL SHE ACCELERATE?
NOTE: TWO forces do NOT CANCEL EACHOTHER OUT

10. REAL-LIFE EXAMPLES!

13. To test Newton’s 3rd Law.... Let’s build rockets...... Sort of.
Every pair will come and get a balloon, blow it up, and release the balloon

14. How did that work (in accordance with Newton’s 3rd Law)?
Is this similar to a real rocket? How?
