# Classes:

### Guidelines:

Each Friday there will a quiz at the end of class. Each quiz will be graded by the recitation instructors and returned during the following week's recitation session. Solutions will be posted the weekend following each quiz. The purpose of our quizzes is to encourage you to keep up with the homework assignments and to permit us to evaluate your progress regularly.

Concept Checks will be an important part of each class. Typically two or three physical situations will be compared and a simple question posed regarding their relative behavior. You will be given a minute or so to think quietly about the question, followed by another minute or so to discuss the question with a neighboring student, where you attempt to work out an answer in consensus. I then ask for a show of hands for each possible answer so that I may determine if you understand the concept well enough to continue.

### Schedule:

The general topic for consideration in each class is listed along with the recommended pre-class reading and post-class exercises. Ch. 22: 1-6 means Chapter 22, Sections 1 through 6 from Halliday, Resnick, and Walker's 5th edition of Fundamentals of Physics. 22: 8P, 18P, 19P means problems 8, 18, and 19 from Chapter 22. Homework assignments for a given class may change up to the time that the class is held. Please check the assignments page for the latest assignment.
