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

Course Objectives
At the end of the course, students will be able to:

• Analyze the motion of particles in space and time, according to Newtonian mechanics.
• Apply the concepts of force, work, and energy to solving mechanics problems.
• Analyze the rotational motion of the rigid solid.
• Analyze the oscillatory motion of basic systems.
• Explore thermodynamic systems at the macroscopic and microscopic level using the laws of thermodynamics.

Lab:
The lab for this class is Physics 2341. You should be signed up for one of the many sections of PHYS 2341, although it can be taken in a future semester.  The lab is graded independently of the lecture class. The labs are held on Tuesdays and Thursdays. Please attend this week because you will have a short, informational meeting with your instructor. Please bring $15 (exact change) to your first lab meeting for the lab manual and notebook. All lab sections are held in Meyer 121.

Textbook:
Physics for Scientists and Engineers, 5th Edition.  By Giancoli.
(Print ISBN-13: 9780134378060, eText ISBN-13: 9780137488179) You need chapters at the beginning and end of this textbook, so don't just get the "volume 1" or "volume 2" versions.

Grading:

Your final letter grade is calculated roughly as follows:

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

Schedule (tentative):

Course Policies:

Canvas will only be used sparingly for this class unless we have to go online. I will primarily use Canvas to show you the homework and test scores that I have for you in my spreadsheet. Compare the Canvas gradebook to your records and send me an e-mail if there is any discrepancy. Ignore any of the letter grades or score averages that Canvas computes independently.

Attendance can affect your grade both directly and indirectly. Attendance is crucial on test days. Sometimes I will call on people to answer questions, or have everybody solve practice problems on a sheet of paper. If you miss such an in-class activity, there is no make-up. I'll record attendance on some days, and an attendance score may be factored in to the "Homework, attendance" part of your grade. 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.  Only then can you schedule a make up (more below). The name and phone number of a relevant authority figure (perhaps a parent) or a cell phone picture (e.g, of you next to your broken down car) 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 it 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.  

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 (basically an attendance check). Do not attempt to "make up" these problems if you miss one, but you can ask me or a student for their notes.
