W 11/2

Th 11/3

F 11/4

### 🔴 2: W 11/2a, 🟡 4: T 11/1 - center of mass problems (1)

Daily Check-in:  center of mass summation  (a similar example if you missed class)

Today, we'll collaboratively solve center of mass problems from Chapter 9:

Support: 2, 4
Required: Sample prob 9.02, 5, 7, 8, 15, 16, 17, 114, G65
Enrichment: 14, G66, G67

These problems will require you to use the calculus and what you learned about different kinds of densities.

HomeworkWork on at least half of the required problems from the set above.  It is very important that you do these required problems.  Also, make sure that you're comfortable with Example 9-14 on page 223 of the Giancoli textbook.  Try recreate the solution the problem from the 3rd and 4th video from last night independently.  That means to write out your own solution without watching the video.  The problem is to find the center of mass of a non-uniform rod length L where λ = kx3.  Then,  answer the following questions in a ✏️ Google Classroom assignment by Friday at 10pm.

If you get stuck, rewatch the videos:

### 🟥 2: W 11/2b, 🟨 4: W 11/2 - center of mass problems (2)

Daily Check-in:  center of mass integral

Today, we'll collaboratively solve center of mass problems from Chapter 9:

Support: 2, 4
Required: Sample prob 9.02, 5, 7, 8, 15, 16, 17, 114, G65
Enrichment: 14, G66, G67

These problems will require you to use the calculus and what you learned about different kinds of densities.

Homework:  Finish all required problems you did not get to in class.  It is very important that you do these required problems.  Also, make sure that you're comfortable with Example 9-14 on page 223 of the Giancoli textbook.  Try recreate the solution the problem from the 3rd and 4th video from last night independently.  That means to write out your own solution without watching the video.  The problem is to find the center of mass of a non-uniform rod length L where λ = kx3.  Then,  answer the following questions in a ✏️ Google Classroom assignment by Friday at 10pm.

### ❤️ 2: Th 11/3, 💛 4: F 11/4a - moment of inertia

Today, we'll spend the period first learning about what moment of inertia is and then trying to figure out how to calculate the moment of inertia of different objects.  We'll learn formulas for moment of inertia using a summation for discrete objects and then an integral for continuous bodies.  With any time remaining, start problems from the next post.

HomeworkQuiz on center of mass, moment of inertia, rotational kinematics, and tipping - Tuesday, November 8th.  If you have any questions about the lecture today, you may watch my video lecture, and make sure you watch the part about parallel axis theorem starting at minute 33.

### 📕 2: F 11/4, 📒 4: F 11/4b - moment of inertia problems

Today, we'll work on problems from Chapter 10 on calculating moment of inertia:

Support: 42
Required: 36, 38, 40, 43, G50, G42, G46
Enrichment: G49, G51

Homework:  Moment of inertia problems due on Sunday, November 6th at 10pm to ✏️ Google Classroom.  Watch the following video by Dan Fullerton on Rotational Dynamics.  Watch ONLY from 6:06 to 19:30!  Take your time working through these examples to really understand them.  It would be a good idea to have these examples written down in your notes.  Quiz on center of mass, moment of inertia, rotational kinematics, and tipping - Tuesday, November 8th.
