HP Cycle 12

🟢❗ 5: M 11/13 - 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.  

Presentation:   Two Block Systems
Homework:  Look over your notes from today's Pear Deck, watch the videos below:

🟩 5: T 11/14 - pulley problems

Today, we'll look at what a pulley does... basically it changes the direction of the force.  Here, we'll start looking at Newton's 2nd Law problems with more than one object in the system.  We'll have to write a ΣF statement for each object as well as the total system.  Then, we'll work on page 5 of Big Newton's Law Packet. (SOLUTIONS to whole packet) 

We'll then solve "table top pulley problems" with #1-2 in Table Top Pulley Problems, Solutions #1-2.  

Optional Challenge Problems:   Two Block Problems #1, 2, and 4.  SOLUTIONS

Homework:  Finish #1-2 in Table Top Pulley Problems, Solutions #1-2 and upload to ✏️ Google Classroom by Wednesday, November 15th at 10pm.  If you need support, watch the videos below (repost):

💚 5: Th 11/16 - 📖 system & pulley problems

Today, in order to reinforce the problem-solving techniques for multiple objects in a system, we'll work on Chapter 5 textbook problems in 📖Mastering Physics "Ch 5.5 - multiple mass systems":  #42, 44, 46, (47 assigned mistakenly), 79, 82, 84.

Optional Challenge Problems:   Two Block Problems #1, 2, and 4.  SOLUTIONS

Homework:  Finish 📖Mastering Physics "Ch 5.5 - multiple mass systems" by Friday, November 17th at 10pm.  Assessment of all of Newton's Laws in 1-D Monday, November 20th.
