Course Description: Physics 262 is the third semester of university physics and it serves as an introduction to thermodynamics, optics, relativity, atomic physics, and quantum mechanics.  Physics 266, or Introduction to Thermodynamics, is a one credit course and it corresponds to the first third of Physics 262 (Chapters 17-20 in the course text).   Be sure to print out a supply of  5 or so copies of this “flashcard” and bring them to lecture.

 

Prerequisite:  PHYS 260. Corequisite: MATH 214.

 

Text: Physics: for Scientists and Engineers with Modern Physics, 3rd Ed by Giancoli.  

 

Grading (Phys 262)

I will compute your score using two methods and take the higher of the two:

Method 1:    Exams 1,2,3 count 15% each, final counts 45%, and recitation 10%

Method 2:    Exams 1,2,3 count 10% each, final counts 60%, and recitation 10%.

For PHYS 266, your grade will be based 90% on Exam 1 and 10% on recitation.

Recitation Policies: The policy on homework will be announced by your recitation instructor, who will also hand out a syllabus explaining how recitations will be graded – in particular, how much of your recitation grade will be based on quizzes, homework, and participation.  You are encouraged to work on your homework assignments together in small groups, but copying homework from each other is not allowed.

Exams:  The exams are closed-book, but you will be given an equation sheet for each exam.  Only equations on the sheet will be considered valid starting points on the exam.  Any other equations you use on the exam must be derived in order to receive credit.  Calculators will be needed for quantitative problems.  It is the responsibility of each student to attend classes during scheduled examinations as listed in the syllabus regardless of work or family considerations. Make-up exams will be given only to students with a VALID medical excuse and they should contact the instructor as soon as they return to school. If you are a student with a disability and you need academic accommodations, please see me and contact the Disability Resource Center (DRC) at 993-2474. All academic accommodations must be arranged through the DRC.

 

E-mail  From time to time I may send the class a mass e-mail, so be sure to activate and check your gmu account.  If you use a different account for e-mail you can arrange to have e-mail to your gmu account forward to you.

 

Snow closings.  If the University is closed because of weather or other emergencies, a test scheduled on that day will be given at the next class meeting after the University reopens.  (Call 703-993-1000 for info on snow closings.)

 

Tutoring.  The physics department has a free tutor (Dr. Shalom Fisher: tel 703-993-1286, sfisher2@gmu.edu), who sees students in his office 3076 DK, and whose hours are posted at: http://ttc.gmu.edu/tutoring.hours.html

The solutions to the even numbered problems are shown in parenthesis next to the problem numbers.  .
