HP Cycle 9

🟢 8: M 10/26 - problem solving

Today, I'll answer any questions you have about the test next class, and I'll give you some time to study.  

Homework: ❗Assessment of all of Newton's Laws in 1-D next class - Tuesday, October 27th.

🟩❗8: T 10/27 - Newton's Laws in 1-D assessment

❗Assessment of all of Newton's Laws in 1-D TODAY!

💚 8: W 10/28 - friction lab 

Today, we'll first look at past assessment performance with quiz corrections.

I'll then take questions on Situation 3 or pulley problems in general.

Finally, we'll introduce the idea of quantifying friction.  We'll talk about where friction is helpful (walking and braking) where it is not (in lab situations). We'll also talk about the difference between static friction and kinetic friction. We'll talk about how to increase the friction between two surfaces (think Mr. Miyagi from Karate Kid). Finally, we'll do a lab to find the mathematical relationship between the normal force and the force of friction.

Handout:  Friction Lab - Write your responses in your journal.
