Practice Quiz Wk 1 (Ch. 19,20).
NTNU Java applets. (Look under "Thermodynamics".)
Wk 1 outline PDF (requires acrobat).
Practice Quiz Wk 2 (Ch. 20).
Wk 2 (Ch.20) outline PDF (requires acrobat).
Practice Quiz Wk 3 (Ch. 21). Note: "D" stands for delta in some problems. Note: this is an old practice quiz so problems don't track coverage perfectly.
Equation review for Exam 1
Exam 1 Key (p1, jpeg)
Exam 1 Key (p2, jpeg)
Practice Quiz Wk 4 (Ch22)
Practice Quiz Wk 5 (Ch15, Oscillations)

Practice Quiz Wk 6 (Ch16) (#11-13 from Ch.18)

Practice Quiz Wk 6 (Ch17). Note: in #7, tension=1006 N.

Equation review for Exam 2. Test includes Entropy material in "Equation review for Exam 1". Some of the longer equations might be provided. Focus on knowing how to use them.

For week 8, Ch. 18 (superposition), review the last two practice quizzes. They contain some superposition-related problems.

Practice Quiz Wk 9 (Ch35) Only the first half are from Ch. 35; ignore the last 5 problems concerning polarization. Typo: answer to #9 is:  a) 4 cm behind the mirror.

Equation review for Final Exam. These are only equations for the last 3rd of the course. For comprehensive review, use the above equation reviews.


Lab:   The lab for this class is Physics 235. It meets in Meyer 122. There are several sections which are instructed by physics profs. TAs who are science majors will grade your notebooks and assist you with the lab. You will have an informational meeting with your instructor on the first week where you will be assigned your first lab.

Text:   Physics for Scientists and Engineers, 7th Edition.  By Serway and Jewett.

Course Description:   This course is a calculus-based introduction to thermodynamics ("Heat"), Sound (including oscillations) and Light (including the optics of lenses and mirrors). These are broad topics in themselves and so only a cursory treatment can be given here. A tentative calendar of topics is outlined below .



Homework, participation



Quizzes (drop lowest grade)



There will be two exams and a final.





Your final letter grade is assigned roughly as follows:











I will not to grade any "harder" than the above. However, if the class mean drops below 75, I will grade more leniently.

Course Policies

Attendance is important for doing well in this course.  Absenteeism can directly lower your grade if you miss a quiz or activity.  Let me know in advance (e-mail is good) if you plan to miss for a valid reason (e.g. your team is on the road, you are sick, you have a family emergency). If you miss a quiz or exam because of an emergency, let me know as soon as possible, and provide proof of the emergency. Proof can consist of the phone number of a parent or authority figure involved.

Homework  will usually consist of working about 15 problems from the textbook.  Problem solving is a major part of physics and so we will use some classtime each week (probably every Friday) for group work on problem sets.   Homework will receive 50% credit if it is late. If you foresee yourself missing a deadline because of an excusable absence, again, let me know ahead of time. Homework will be scored on completeness and correctness, but not every problem will be corrected. Show the steps leading up to your answers, and box in your final answers. It is acceptable to compare with your peers and the textbook's answers, but you should strive to understand how those answers were obtained. Do not turn in paper with frayed edges.

Quizzes will be given on non-exam weeks.  They will consist of 5-10 multiple choice/short answer questions.  They cover the assigned reading and especially the material discussed in class.  You can only make up a quiz that was missed because of a valid conflict or emergency.  Also, you can only make up the quiz before the answers are revealed (usually the next period). For this reason, I will drop your lowest quiz score. I provide online practice quizzes each week to help you prepare for quizzes, but these are not graded.

Exams will be given roughly every 3 weeks. These will weigh most heavily towards your class grade. The final exam will be comprehensive, but will emphasize the last 2-3 weeks of material.

Disruptions.  You can ask questions during class, and talk during group activities, but other talking disrupts the concentration of the other students and your instructor. Arriving late is also disruptive.   Class begins at 12:00 PM.  Don't be late or you may face public humiliation. You might also miss a quiz.   In general, do not disrupt the class or you may be asked to leave.

Cheating will not be tolerated. During tests, do not use outside references UNLESS I explicitly allow them. Do not look at another person's quiz or exam while you are taking one. Also, if you suspect someone is copying your answers, try to prevent it by moving or shielding your answers. If I think you are copying, I can give you a zero score for the quiz or exam.

Calculators. I encourage you to use a scientific calculator in this class. Do not use it to store equations or do calculus for you. These are things you must learn.

Tutoring is available from different sources. First, you are welcome to drop by during my office hours, or you can make an appointment with me. Second, there will be upper level science students (especially physics majors) that will offer their services. And third, there is a hired science tutor in Engineering and in Physics (Arts and Sciences) that should be available.  In the past, tutoring usually occurs on Wednesday and Thursday evenings, from 7:00-9:00 PM. Stay tuned.
