HP Cycle 10

🟢 5: W 10/30 - 📖 friction problems

Today, we'll first recap with this Friction Presentation.  If you did not watch the friction video, watch that first.  Then, we'll work on on friction problems collaboratively.  Work on problems from Chapter 5 in your 📖textbook:  #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:  No Homework Night.  Optionally complete textbook problems above.  Quiz on Newton's 2nd Law problems (including elevator problems) PLUS friction Monday, November 4th!    

🟩❗ 5: M 11/4 - 🟢❗ 5: M 11/13 - Newton's 3rd Law & 2-block systems

Quiz on Newton's 2nd Law problems (including elevator problems) PLUS friction Today!

After the quiz  Today, 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.  

Then, 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)

Homework:  Look over your notes from today's presentation, watch the videos below:

💚 5: T 11/5 - 📖 2-block system problems

Today, we'll work through a few 2-block system problems.  This will be the last topic which will be covered on the test.  

In order to reinforce the problem-solving techniques for multiple objects in a system, we'll work on Chapter 5 📖textbook problems from section 5.5:  #42, (44), 46, 79, (82), (84).

Homework:  Finish 📖textbook problems above.  Assessment of all of Newton's Laws in 1-D on Tuesday, November 12th (last assessment in 1st marking period).
