Recitations

See the Recitation Schedule for times and rooms. This page applies only to sections taught by Dr. Yost.

The only way to understand the course material is to work through it on your own. Watching someone else work through it will not help you learn it. To get the most out of the recitations, please begin to work on the problems as soon as the lectures begin on a topic. The problems are not graded. The recitations are your chance to ask questions on the material and be sure you understand everything. Do not be afraid to participate in class. Learning is best when it is interactive. The recitations will be helpful only if you have attempted to work through the problems before coming. Yes, the pace is fast. There is much material to cover. It is important to keep up with the lectures, and not get behind on the problem assignments. The problems listed for each recitation should be finished by the date shown. The schedule is subject to change, depending on the actual pace of the course. See the homework schedule for details.

Laboratories

Lab Final The lab final answers are available as PDF files. Explanations are included. Select Version 1 or Version 2, depending on which test you had. If you don't remember, the answers are actually the same: only the order of choices is different. The grades have been posted. The exam is worth 100 points, and the raw scores were multiplied by a normalizing factor of 5/4 before recording them. The normalized average was 52.7.

See the Laboratory Information for Your Section for important information concerning the laboratories and their grading. The laboratory grade is based on laboratory reports on each experiment, and makes up 10% of the course grade. You cannot pass the course if you fail the laboratory. Attendance is required at every laboratory session.

I have some notes on the spring mass coefficient in the Hooke's Law experiment, if you want to see the more precise value than in the lab instructions.
