HP Cycle 14
11/28 - 12/1
🟢 5: M 11/28, 🔵 7: T 11/29 - 📖 friction problems
Today, we'll finish going through the Friction PowerPoint if we haven't finished last time. Then, we'll work on on friction problems collaboratively. Work on problems from Chapter 5 in your textbook in 📖 Mastering Physics "Ch 5.5 - friction problems": #27, 29, 31, 32, 71, 73
Optional Extra Practice: #11-17 on page 2 of Big Newton's Law Packet. SOLUTIONS to pp 1-2 of Packet.
Homework: Finish 📖 Mastering Physics by Wednesday, November 30th at 10pm. I recommend that you finish earlier (tonight) so that you can ask questions before the next quiz. Quiz on Newton's 2nd Law problems (including elevator problems) PLUS friction Thursday, December 1st!
🟩 5: T 11/29, 🟦 7: W 11/30 - Newton's 3rd Law
Today, we will start to explore Newton’s Third Law through interactive lecture and demonstrations. The law states, “If two bodies interact, the magnitude of the force exerted on object 1 by object 2 is equal to the magnitude of the force simultaneously exerted on object 2 by object 1, and these two forces are opposite in direction.” The important thing to remember is that action-reaction forces act on different objects!

Homework: Quiz on Newton's 2nd Law problems (including elevator problems) PLUS friction next class - Thursday, December 1st! Watch the following videos as a review of Newton's 3rd Law:
💚❗ 5: Th 12/1, 💙❗ 7: Th 12/1 - two block systems
Quiz on Newton's 2nd Law problems (including elevator problems) PLUS friction Today!
After the quiz, we'll start by doing a problem with an applied force on a system of two blocks. Remember, when we have two blocks, then we can draw a free body diagram of each object as well as draw a third free body diagram of the system as long as both objects have the same acceleration.
