DESCRIPTION & OBJECTIVES: The aim of this course is to continue, merge and extend the studies of Classical Mechanics I PHYS-302 in previous semester. Its ideas also link with other courses like quantum mechanics and condensed matter. The fundamental goal of this course is to create understanding in students to classical mechanics and its applications. This course provides the students the up-to-date treatment of classical mechanical systems and serves as basics and pre-requisite of Quantum Mechanics so that students face least difficulty in entering from classical Physics to Quantum mechanics. The purpose of the course is to make the students capable in formulating and solving physics problems.

Learning Outcomes:

After completion of the course, students will be able


1- To deal with, central force motion and system of particles and related phenomenon.

2- To write the equations of motion for complicated mechanical systems using the Lagrange's and Hamilton's equations of motion.

3- To develop problem solving approach and critical thinking, Students will be able to solve problems in applied physics.

4- To start advance fields of Physics like quantum mechanics and field theory on the basis of Lagrangian and Hamiltonian technique.
