Mechanics-II: Course Content

Course Code: PHY 1101

What is Mechanics

Mechanics is the branch of Physics dealing with the study of motion when subjected to forces or displacements, and the subsequent effects of the bodies on their environment.

Objectives

The main objective of this course is to acquaint students with rotational dynamics of objects on a macroscopic scale and to develop simple mathematical formalisms to analyze such motions. This is a calculus-based introductory course with maximum emphasis on applying the acquired knowledge to solving problems. Also, a general formalism of Special Theory of Relativity is given.
