CPS mode and some exercises I like from chapters 4 and 5

Our midterm exam on Wednesday will cover topics from chapters 2-4 and as much of chapter 5 as we cover by end of class Monday.

We will also have a short in-class review session in the last 20 minutes of class, using CPS. It will be in SMA mode, "student managed assessment," which means you will have a handout of a dozen review questions to work on, and you type in your answers at your own pace. The clicker will tell you which question you are on.

We will use SMA on the midterm exams, so be sure to bring in your clicker on Wednesday, too.

Here is a list of exercises and examples I like in the textbook and the problem-solving manual (PSM).

1. Chapter 4
   
   
   
   1. PSM: 4.3.2, 4.2 and problem 16 on p. 39
   
   
   2. Textbook, p. 73: exercises 1-4, 7-12, 14-16.
   
   
   
   


2. Chapter 5
   
   
   
   1. PSM: geosynchronous orbit 5.5.1, and problem 4 on p. 45
   
   
   2. Textbook, pp. 91-92: exercises 3 and 4, 5 and 6, 7 and 8, 9 and 10, and two sweeeeeeet brainburners 11 and 20.
   
   
   
   

Exercises I like in chapter 3.

Here are some exercises I like from chapter 3.

1. Exercises 1-16 on p. 54
2. plus exercises 21-14 on p. 55
3. Examples 3.2.1-3.2.4 in the problem solving manual, Problem Solving for Physics: A World View.

Exercise 21 on p. 55 is a brain burner.

On Monday, I will post MY written solutions for these and other exercises, so that you can check your work. They'll be in the glass display case in the third floor of MAP, across from room 337. Here is a photo of it.

Caught nappin'

Take a look at the Lecture Files in Webcourses. There is a file for exercise 10, p. 73, which we were working on at the end of lecture. I made an error in the orbital speed computation, which was spotted by Morris and Katherine. The new lecture file for exercise 10 has the correct computation, along with some comments on the law of universal gravitation in chapter 5.

Gracias, Katherine and Morris!! I was nappin'!!

Thursday's lecture = GO

We will have regular lecture on Thursday morning, back to the normal schedule.

Thursday's lecture will be on gravitation, so do some reading and skimming in chapter 5, if you have 30 min. Especially look at the diagrams and illustrations. We will review and elaborate the blurb on p. 81, "Working it out|Gravity" plus some of the exercises on circular motion and orbits from chapter 4, p. 73:

1. exercise 8, generic circular motion;
2. exercise 9, Earth-Sun orbital system;
3. exercise 10, Earth-Moon orbital system.

You can eyeball those tonight and maybe bug Ashton and Meg with questions in Discussions. :)

See you Thursday morning, GO FOR LAUNCH!

Extra questions and exercises; glass display case

I just set up the list of extra exercises and questions in chapter 20 that I like. Look in the homework area (yellow pickup truck) and click on the horseshoe magnet icon for the list. It has a few comments with it.

I will post the photocopies of the exercises I worked out in chapter 17 and chapter 20 this afternoon, right before walking over to the bookstore for office hours. Look in the glass display case across from room 337 in the MAP building.

Three new problems on Uvision podcast

There are three exercises visually podcasted now on the Uvision website. These are three of the exercises that I like in chapter 11. I have a few more to publish but these will hold you for now.
