HP Cycle 13

🟢 5: F 11/18, 🔵 7: M 11/21 - 📖 Newton's 2nd Law problems

Today, we'll practice with Newton's 2nd Law by working through some 📖 Mastering Physics problems from Chapter 5 in your textbook "Ch 5 - N2L 1-D basic problems": #6, 9, 11-13, 15, 19-23, 53, 55, 60, 64.

Homework: Finish the 📖Mastering Physics problems by Tuesday, November 22nd at 10pm. I would recommend finishing these problems early (before next class) so that you can ask questions if you have any trouble.

🟩 5: M 11/21, 🟦 7: T 11/22 - friction lab

Today, 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 on a separate sheet of paper to be turned in.

Virtual Alternative: LAB - Friction (virtual) if you are absent. Make a copy into your own Google Drive.

Homework: Finish what you can in the Friction Lab. Whole lab is due Tuesday, November 29th, but you really should be able to finish it in class.

💚 5: W 11/23, 💙 7: W 11/23 - friction recap

Today, if you haven't finished the friction lab, we'll start there for about 15 minutes. I will collect the Friction Lab worksheet Tuesday, November 29th, but you really should be able to finish it in class.

Then, we'll begin considering friction in our problems by reviewing the concepts that we should have taken away from the lab and then formalize the concepts in Friction Powerpoint. We'll also do some sample problems in the Friction Powerpoint.
