COURSE DESCRIPTION

The topics we will cover include rigid body equations of motion, oscillations, relativity, the Hamilton Equations of motion, canonical transforms, Hamilton-Jacobi theory and action angle variables, classical chaos, canonical perturbation theory, Lagrangian and Hamiltonian formulations for continuous systems and fields.

COURSE GOALS

Students should experience phenomena describing and/or motivating the laws of physics or physics models
Students will understand the motivation and quantification of the laws of physics
Students will master the construction fundamental physics models from laws, standard techniques and standard methods

COURSE OBJECTIVES

COURSE REQUIREMENTS AND POLICIES

Course prerequisite or corequisite:

Attendance: Attendance is not mandatory but highly recommended. Many homework and exam problems will be based on work and examples done in class.

Homework: Homework will be assigned each week on a Monday. It will be due the following Monday in lecture. Each assignment will be approximately 5 problems. Each homework assignment will be approximately 100 points. THERE IS NO LATE HOMEWORK!

Exams: The midterm exam is worth 20% of your grade. The final exam is worth 30% of your grade. The midterm is on Friday, 10/09/09 in class. The final is on 12/03/09 from 10am - 12 noon in room 111. All exams are closed book and no electronic devices are allowed. Bring only a pen and pencil.

Grades: A student’s grades in the class are based on a composition of 50% homework, and 50% for the exams.

Cheating: Cheating of any kind will not be tolerated. Please refer to the Howard University Handbook (H - book) for university guidelines on cheating. No talking under any circumstances is permitted during an exam. If help is needed simply contact the instructor. In addition, only a pencil is required for all exams; notebooks, calculators, and scratch paper will not be needed.

Required Textbook: Goldstein, Poole, and Safko. Classical Mechanics. Third edition, Addison-Wesley. San Francisco.

General Policies: All lectures and recitations may be videotaped and NOT made available to the general public.

Howard University is committed to providing an educational environment that is accessible to all students. In accordance with this commitment, students in need of accommodations due to a disability should contact the Office of the Dean for Special Student Services for verification and determination of reasonable accommodations as soon as possible after admission to the University, or at the beginning of each academic semester. The Dean of the Office for Special Student Services, Dr. Barbara Williams, may be reached at 202-238-2420
