Class time and place:  MWF, 12:00-12:50 pm, Meyer 113 (Section 4)

Lab:
The lab for this class is Physics 2341. You should be signed up for one of the many sections of PHYS 2341.  The lab is graded independently of the lecture class. If you have a Thursday section, you will have a short, informational meeting with your instructor on the first week (you will be assigned your first lab, etc). If you have a Tuesday section, make sure that you pick up a lab manual and notebook at the Physics Office (SA107) this week. Go to Meyer 121 for these labs.

Text: Physics for Scientists and Engineers, 8th Edition.  By Serway and Jewett.

Course Description:
This course is a calculus-based introduction to the physics of solid bodies. Topics include motion in 1, 2, and 3 dimensions, forces, Newton's laws, energy, momentum, and rotational motion. A tentative calendar of topics is outlined below .

Grading: Homework & in-class 25%, Quizzes 25%, Exams 50%

Your final letter grade is calculated roughly as follows:

<55

55-70

70-80

80-90

90-100

F

D

C

B

A

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

Course Policies

Attendance. can affect your grade both directly and indirectly. Attendance is crucial on exam days, quiz days, or due dates. In-class activities and questioning will be done using my attendance sheet. If you miss an in-class activity, there is no make-up. The attendance may be used to determine boarderline grades. Absences can also indirectly lower your grade because the material presented in class reflects the material on quizzes and exams.  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 unforeseen emergency, let me know as soon as possible, and provide proof of the emergency. The name and phone number of a relevant authority figure (perhaps a parent) can be provided as proof. Do not book flights or make other plans that conflict with the final examination time.

Homework. will consist of working problems from the textbook and from the instructor.  Problem solving is a major part of physics; you must practice to really know it.  I hope to provide some practice questions from a test bank each week. These do not have to be turned in, but can be considered a homework "supplement".    Homework turned in after the due date (usually Friday afternoon) will be given 50% credit. If you foresee yourself missing a deadline because of an excusable absence, again, let me know ahead of time.  

In-class problems.  These problems will count towards the homework portion of your grade, although they will be done in-class (hence the name).  Grading will be lenient, but if you miss these problems there is no making them up.

Quizzes. will be given on most non-exam weeks.  They will consist of 5 - 10 questions, mostly multiple choice.  They cover the assigned reading, homework 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.

Exams. will be given roughly every 5 weeks. These will weigh most heavily towards your class grade. The final exam will be comprehensive, but will emphasize the last 5-6 weeks of material.

Disruptions.  You can ask questions during class and even snicker when I tell a joke, but don't interfere with the learning of the students around you. Don't habitually walk in too late.   Do not use cell-phones and don't text in class.  If you really think you can take notes better on a laptop then in a notebook, then you can.  But if it distracts the class, I'll ask you to stop.   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 like laptops, textbook, or notes UNLESS I explicitly allow them. Do not look at another person's quiz or exam while you are taking one.   Do not make it easy for another person to see your answers - if anything shield your answers. Do not share calculators during an exam unless you check with me.  Do not store equations in your calculators.  The penalty for cheating is as severe as a zero score for the quiz or exam.

Calculators. I encourage you to use a calculator in this class.  But instead of storing functions in the memory of your calculator, store them in the memory in your brain. If you do not submit your calculator to me for an inspection when asked you will be denied the right to use one.   

Tutoring. is available from Physics, Engineering, and Math.   (Physics tutors usually work on Thursdays from 7-9 PM in SA116.)   Listen for a confirmation in class.   Of course, you are also welcome to drop by during my office hours.
