HP Cycle 15

🟢 6: W* 12/2, 🔵❗ 8: Th 12/3 ➕PP Newton's 2nd Law problems

Pd 8 QUIZ - Freefall Problems

Today, we'll practice using ideas of Newton's Second Law in ➕ Positive Physics from unit 5: introduction to forces:

• complete problems 1

• complete problems 2

• complete problems 3

• complete problems 4

Homework: Finish ➕ Positive Physics problems in unit 5 by Saturday at 10pm. Only completion score will count, so you can continue to try if you get it wrong the first time. Try to finish these problems early in case you run into technical difficulty. No late credit. Quiz on freefall problems on Thursday, December 3rd!

🟩❗ 6: Th 12/3, 🟦 8: F friction lab (1)

Pd 6 QUIZ - Freefall Problems

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.
