Physics 125: Spring 2006
Classical Physics A

Physics 125 is a course in Classical Physics intended for students at the freshman and sophomore level. The course provides an introduction to classical mechanics through rotational motion,rigid body equilibrium and gravitation. This material is covered in chapters 1 through 12 in Young and Freedman, the required text. The course is intended for majors in Physics as well as other sciences, mathematics and engineering. The course consists of three lectures, a two hour laboratory, and a one hour recitation per week.

1. Required material:

Textbook: University Physics (11th edition) by Young and Freedman
PHY 125 Lab descriptions, available for free by download in PDF format.
Lab Notebook: (77610 or equivalent)
Scientific Calculator (with trigonometric functions) for homework problems, laboratories, recitation quizzes, and exams

2. Lecture:

MWF, 8:30-9:25am, Physics P-113
Instructor: Sasha Abanov, Office B-102, phone 632-8174

Office Hours: Mon 9:30-11:30am

You are responsible for all announcements made in lecture You should read the assigned text material before it is discussed in lecture.

3. Homework:

Every Monday in the lecture a set of homework problems will be assigned. The homework is due the following week in the recitation.

4. Recitation:

The recitation provides an opportunity for informal discussion of the course material as well as the homework problems. Attendance in recitation is mandatory.

5. Laboratory:

Starting the week of January 30, you will perform a set of experiments illustrating the material discussed in the lecture. After writing up the result of each experiment you will hand in your lab report to your instructor at a time to be determined. All lab data and your report must be in your lab notebook. The lab report is due within 48 hours after the lab section. There will be point deductions for late hand in (one-point out of 10 per day). Your report will be graded and returned to you at the next lab meeting. You are expected to perform and write up all laboratories. Failure to do so will result in severe deductions from your course grade including possible failure of the course. Details regarding the handing in and grading of lab reports will be provided at the first lab meeting. A schedule of laboratory meetings and lab descriptions for download can be found here .

6. Exams:

There will be two midterm exams and a final exam on dates indicated on the attached lab and exam schedule. Midterm exams will be given during the regular lecture hour at locations to be announced in lecture.

7. Grade:

Your final grade will be determined by weighting the various portions of the course as follows:

Each Midterm --- 17.5%
Final exam --- 35%
Recitation --- 10%
Laboratory --- 20%

8. Help:

The course instructors will be available during office hours and by appointment for help with questions related to your homework problems and and/or general understanding of the course material. For questions concerning the laboratory you should see your laboratory instructor. You are encouraged to come and ask questions; we are here to help you master the course material. ABOVE ALL - do not get behind; it is very difficult to catch up in a Physics course. We urge you to seek help at office hours as soon as you have any difficulty, not just before exams.
