Classical Mechanics-I
Offered By: Banaras Hindu University via Swayam
Course Description
Overview
ABOUT THE COURSE: This is first course to introduce the concepts of Classical Mechanics which is pre-requisites for more advanced courses like Advanced Classical Mechanics, Quantum Mechanics, Statistical Mechanics, Classical and Quantum field theories. In this we will learn mainly Lagrangian and Hamiltonian formulation in a very simple manner with many examples along with theory of small oscillation and two body central force problem. This will be helpful to students who will be writing national level examinations like NET, GATE etc.INTENDED AUDIENCE: 3rd Year UG students and/or 1st Year PG studentsPREREQUISITES: 1. Mechanics2. Elementary Mathematical Physics (Calculus, Matrices, Vectors)
