- NEW As mentioned in class, I am uploading the general proof for the decomposition of kinetic energy into contributions OF and WITH RESPECT TO an arbitrary reference point (A). Long story short, this decomposition only works if either
(1)(A) is stationary or(2)(A) is the Center of Mass position. You can find the full derivation here.Wednesday, Feb. 22, 2017

- The formula sheets for Midterm #1 (and Midterm#2 and the Final) can now be found on the Homework page. This will be provided with the exam, as will the 1D and 3D calculus formulas.

- Useful formula sheets have now been added to the Homework section of the webpage.
Tuesday, Jan. 24, 2017- Anything on these sheets do not have to be proved in this course. Take a minute to look through them to see what is there.

- Due to room availability, the room and time of Thursday office hours have been changed.
Friday, Jan. 20, 2017- Please check below for updated information.

- Website is up!
Monday, Jan. 17, 2017- Please take a minute to read through the general course information on this page, which explains the course structure and policies on homework and grading. Also included is a link to the course syllabus, which provides a week-by-week breakdown of topics covered in this course and suggested reading. Specific information on office hours will be included in the coming days.

Course Description- This course constitutes a core requirement for Physics majors or minors at the University of Illinois, and covers major topics from the field of classical mechanics. Topics covered include the kinematics and dynamics of classical systems, including a review of Newtonian kinematics and dynamics; three dimensional motion, variable mass, and conservation laws; damped and periodically driven oscillations; gravitational potential of extended objects and motion in rotating frames of reference; Lagrangian and Hamiltonian mechanics.

Course Grade BreakdownHomework will be 25% of the total grade, discussion attendance 5%, and exams will count for 70%. Two mid-term exams are worth 15% each, and the final exam is 40%. Homework due dates and timeHomework assignments will be posted each week on Friday, and are due at 1:00 pm on the following Friday. Your solutions are to be deposited in the course homework box that is located on the second floor of Loomis Lab, at the entrance to the overpass to the Materials Research Lab (MRL) on the north side. Assignments which are late, but handed in by Monday at 1pm will lose 15%. Another 15% will be lost (30% total) for assignments submitted by Tuesday at 1pm. No late assignments will be accepted after Tuesday at 1pm! For assignments due within a week of a midterm exam, no late assignments will be accepted.General Policy Regarding GradingHomework is considered essential to learning course material, and should be treated as training for future work rather than as a test of what you already know. You should start working on an assignment early, close to when it is posted on Friday. We encourage students towork together, andget helpfrom the professor or TAs when they encounter difficulties. We will happily explain difficult concepts during office hours and check your work for errors. For this reason, scores on homework are typicallyhigh(~95%). Don't make the mistake of starting your homework the day before it is due! (You know better.)

Partial credit will be given on homework and exams if and only if the work is coherent. A random scattering of thoughts will not be awarded points. Simple numerical errors will not be strongly punished, however students are expected to be careful about their work and will lose points for errors which give incorrect physical results. The steps to receiving partial credit are: (i) write your solution neatly and coherently using equations and words to describe what you are doing (ii) checking your answer for consistency e.g. are units correct, does the solution behave correctly in known limits? Write as though you are explaining the problem to somebody who doesn't already know the answer! Expect the exams to be challenging but to be curved accordingly.
