Course Objectives

Objectives:
The aim of this course is to provide a solid understanding of the fundamental aspects of classical mechanics. These aspects of classical mechanics endowed with a concrete background in understanding the contemporary fields such as Special Relativity, General Relativity and Quantum Mechanics etc.
Outcomes:
On successful completion of this course, students will be able to
 Develop the Lagrangian and Hamiltonian for the system under study.
 Obtain the equations of motion.
 Solve the equations of motion for different cases.
 Apply the concepts of canonical transformations and Poisson brackets.
 Treat rigid body rotations from the stand point of matrix transformations.
 Applying Hamilton’s Jacobi techniques to solve the motion of mechanical systems.
