3. Course Objectives

Classical mechanics is studied using mathematical tools. Topics include kinematics, dynamics, central forces, many-body systems, motions of rigid bodies, Lagrangian and Hamiltonian formulations. The goal of this course is (1) to develop fundamental concepts in mechanics as needed for further study in physics and engineering and (2) to learn how to apply physical concepts and mathematical techniques to solve practical problems in classical mechanics.

4. Prerequisites & require

General physics 1, Vector Calculus, Differential Equations
