🟒 5: M 11/28, πŸ”΅ 7: T 11/29 - πŸ“– 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 πŸ“– 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 πŸ“– 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, β€œIf 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:

πŸ’šβ— 5: Th 12/1, πŸ’™β— 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.
