Digital Agenda September 16: Newton's 3rd Law Cornell Notes

Standards:
MS-PS2-2:  Plan an investigation to provide evidence that the change in an object’s motion depends on the sum of the forces on the object and the mass of the object.




Objectives

·     1. Students will explain that Newton's 3rd Law demonstrates that forces exist in pairs that are equal in size an opposite in direction by completing the Newton's 3rd Law Cornell Notes with a 3 or better.

1. Do Now: Newton's 3rd Law Pre-Quiz


Independent
1. Watch THIS VIDEO and take the Newton's 3rd Law Cornell Notes:

Vocabulary
Newton's 3rd Law
Force Pair
Reaction
Momentum
Velocity
Conservation of Momentum
Elastic Collision
Inelastic Collisions
Compression



Questions
1. Why do tackles in football related to Newton's 3rd Law of Motion?
2. Why is momentum an important part of Newton's 3rd Law?
3. What does the formula P=mv stand for? What do the variables mean?
4. (not from the video) Calculate the momentum of a football player who has a mass of 100kg and is running with a velocity of 2m/s.
5. Explain how momentum is conserved in a tackle.
6. Draw and explain how the Conservation of Momentum is shown in a Newton's Cradle.
7. Why is a Newton's Cradle considered an elastic collision?
8. Why is a tackle on the football field considered an inelastic collision?
9. Describe how energy is lost in a tackle (an inelastic collision).
10. When one player tackles another player, are the forces they experience different in size, or equal in size? Why?

Summary: Today I learned.....



Cornell Notes Criteria for success:
- Notes are set up in Cornell Note format

NP = none of the success criteria is met


Optional (ONLY AFTER YOU ARE FINISHED!!!!)
1. Watch THIS BILL NYE on Momentum

2. Play with this PhEt simulation to explore how changing masses affect the amount of force needed to move an object

2. Play the NET FORCE GAME and try to beat a score of 6 (the highest anyone has scored has been 19)

3. Watch THIS VIDEO on roller coaster Physics

4. Play the roller coaster building game
