Class Objectives
/Class Outline
Mechanics is one of the mainstays of physics and engineering as well as electromagnetics, and hence an important subject for students in the department of science and engineering as a foundation to be acquired.

Our goal in General Mechanics is to systematically provide the principles and laws of mechanics for engineering students. Students coming out of this class should have a deep conceptual understanding of classical Newtonian mechanics. This course, General Mechanics I, provides instruction in one-particle dynamics and mathematics required for the understanding of this lecture.
