Marion and Thornton
Classical Dynamics of Particles and Systems
4th Ed..

Material to be covered:
Portions of Chs. 6,7,10,11,12, and 13 (Not all in this order!).
Ch. 6.   Brief Overview of Calculus of Variations.
Ch. 7.   Hamilton’s Principle - Lagrangian and Hamiltonian Dynamics.
Ch. 10. Motion in a Non-Inertial Reference Frame.
Ch. 11. Dynamics of Rigid Bodies.
Ch. 12. Coupled Oscillations
Ch. 13. Continuous Systems: Waves.

Several concepts and techniques covered at this level of mechanics are useful in other parts of physics: e.g. minimization principles in various fields; the Hamiltonian and conjugate variables in quantum mechanics; coupled oscillations and normal modes in solids.

The following absolute scale will guarantee the grade listed (except see just below)

Two numbers will be calculated, with the larger of the two determining the grade.
#1: Homework Score (out of 33) + Midterm scores (out of 34) + Final Exam Score (out of 33)
#2: 3/2 x (Midterm scores + Final Exam Score).
Except, that in case #1, a 2.0 will also require 27 or higher on the exams alone, and 2.5 or higher will require 34 or higher on the exams.

If the average on the final exam comes out to be less than 20/33, the instructor may, if he deems it desirable, multiply each final exam score by the ratio (20/actual avg.) to bring the average up to 20/33, and then use this multiplied number in each of the above two calculations.  However, no student may receive more than 33 points for the Final Exam.

Homework will be assigned on Friday or Monday and will always be due the following Friday at the start of class.  At the end of the semester, the maximum possible Homework total will be renormalized to 33 points (probably out of about 240 actual points).

Learning physics is a ‘contact activity’--- you learn it by applying it.  It is best to work a homework problem by yourself if you can.  But there is evidence that it is better for students to discuss problems with each other than to fail to complete the problems.  For this reason, YOU ARE ENCOURAGED TO DISCUSS HOMEWORK ASSIGNMENTS AMONG YOURSELVES, AND WITH ME, BUT YOU MUST WRITE UP YOUR HOMEWORK YOURSELF--NO COPYING. Late homework will be accepted until solution information is provided, with increasing penalty the later the date.
