Physics 241E, Fall 2003

GENERAL PHYSICS II

 

 

Physics 241E is a calculus-based introductory physics course covering electricity and magnetism along with a general treatment of waves and an introduction to quantum phenomena. It is part of the required Engineering School curriculum.

Times: MWF 9:00 - 9:50 am and 10:00 – 10:50 am (each P. Fishbane)

Locations: Physics Room 203 -- overflow in Room 205

Instructor: Paul Fishbane: 321 Physics Building, (434) 924-6578, e-mail: pmf2r@virginia.edu, Office hours 12 noon – 2 pm on Wednesdays and by appointment.

Required text: Physics, vol 2, Fishbane, Gasiorowicz, and Thornton, 2nd edition (Prentice Hall) along with material on waves from vol 1 (spring semester text); The Princeton Learning Guide, 2nd edition (Prentice Hall). Physlets (packaged with vol 2).

 

 

 

                    The aim of this course, which is a continuation of Physics 142E and has as a prerequisite the material of that course, is to teach you to understand the physical world and to solve problems about that world. Both elements are important to you. Your grade in the course will depend on your ability to solve problems, but an understanding of the material is crucial to your ability in problem solving, as is the acquisition of a set of skills in problem solving. The lectures are oriented towards helping you understand why and how we understand what we do about physics, not simply towards helping you learn how to plug in formulas in order to solve problems, and not simply towards helping you pass tests. There are extensive office hours, led by a set of teaching assistants, where problem examples and problem help will be treated more explicitly. Understanding the material is the best long-term way for you to be able to solve the problems that an engineer faces. Read each assignment before the lecture and again as soon as possible after the lecture.

 

 

Course Structure:

How your grade is determined:

Homework: 30%

Exams: 20% for each of two midterms and 30% for the final exam

Two midterm tests:

Wednesday, October 1 and Wednesday, Nov 5.

You may take either exam on a given date, but not both! To do so is an honor violation.

Note: No make-up exams are given! With a valid excuse before the exam, the remaining elements of the course will be appropriately averaged. Without a valid excuse before the exam, the exam grade will be a zero.

The exams are multiple choice, of the same type as were given in 142E.

Two final exam periods:

Wednesday, 10 December 2003, 1400 – 1700 (for the 9–9:50am Section)

Tuesday, 9 December 2003, 0900 – 1200 (for the 10 – 10:50am Section)

You should attend the period for which you are officially registered.

 

 

 

Workshops: The workshops (www.phys.virginia.edu/classes/241w.gdc4k.fall03) are labs, which will be completed in groups. All students should register for a workshop section. You must attend the first meeting on time, or your name will be dropped from that section. You must also buy the manual, which is available in the UVA bookstore. The workshops are an enjoyable way to work with your peers and increase your understanding of physics. Please note that the workshops are not formally part of this course but rather a separate entity and must be signed into or out of separately.

 

Homework: Homework for 241E is due each week at 5 am Sunday morning. You will access and answer the questions electronically, via https://www.webassign.net/uva/login.html. 

(The homework assignments are listed below.) Online instructions for webassign are available here. Your username is your UVA user ID; mine, for instance, would be “pmf2r”. Your password is your standard Uva computing password. Note that this is different from last year’s procedure; webassign itself will also look different. You have more time for the first homework set and you can have as many as 10 submissions for this set alone. All subsequent sets will allow you 5 submissions.

 

Getting help on the homeworks:

- The TA’s for PHYS 241E will have the office hours listed below, and they will be available for help with the homework or lecture material.

- The engineering school also provides tutoring assistance. Current sessions are Sunday, 6-8 pm, and Monday, 6:30-8:30 pm, in THN D221.

- The instructor holds the formal office hours posted above. Students are welcome to come by during these office hours, but with over 200 students in each section, it will unfortunately be hard to give much personal attention to any individual. We suggest that the TA's be your first resource for help with the material, and that you contact the instructor only with larger issues that the TA's cannot resolve. For the same reason, there will be no help available on the problems over the phone or by email.

 

 

®Attendance policy: Attendance is not taken, but you are responsible for all assigned material, whether it is presented in lecture or not. You are also responsible for knowing the problem assignments and for any announcements that may be made in lecture of changes in the assignments, schedule, etc.
