Physics 142E is a calculus-based introductory physics course covering Mechanics and Thermodynamics. It is part of the required Engineering School curriculum.

S. Conetti, room 217 High Energy Physics building (434) 982-5371, e-mail: conetti@virginia.edu. Office hours 11-12 on Mondays and Wednesdays, room 312 B in the Physics Building or by appointment.

R. Minehart, room 165 in the Physics Building (434) 924-6785, e-mail: rcm4y@virginia.edu. Office hours 2:00-3:00 pm Mondays and Wednesdays or by appointment.

Required text: Physics, vol. 1, Fishbane, Gasiorowicz, and Thornton, 3rd Edition (Prentice Hall).

The aim of this 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 discussion sessions, led by a teaching assistant, where problem examples will be treated more explicitly. Understanding the concepts is the best long-term way for you to be able to solve the problems that an engineer faces. Problem solving skills are honed by doing problems. You should look at more problems than the ones assigned as homework, at least to convince yourself that you would know how to handle them. Feel free to consult with each other on how to do the problems, but don't put yourself in the position of just copying answers from your partner. And, to validate your approach to any given problem, feel free to consult the TA (or the course instructor during his office hours). But be aware that the TA will be instructed not to give explicit information on how to solve any given homework problem.

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 midtem exams will be a mixture of problems (like the ones you do in the homework or in the discussion sessions) and of conceptual, multiple choice questions; the final exams will be multiple choices.

Workshops: The workshops ( www.phys.virginia.edu/classes/241w.rmm5a.fall04) 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 142E is due each week at 5 am Monday 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, your password is your standard Uva computing password. All sets will allow you 5 submissions (except for the first one, when you will be allowed 10 submissions in order to allow you to practice with webassign).

- The TA for PHYS 142E will have the hours listed below, and will be available for help with problems or lecture material. During these sessions , which will last 50 minutes each, you will be reminded of the basic concepts you have learned in class and then will be shown how to solve various problems related to the ones assigned as homework.

- The engineering school also provides tutoring assistance, consult the Dean's Office for specific hours.

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..
