Learning Outcomes
Upon successful completion of this course students should be able to:
- Demonstrate understanding of the basis of different formulations of classical mechanics and their advantages in addressing different aspects of the description of mechanical systems.
- Demonstrate familiarity with the all-important connections between conservation laws and world symmetries like symmetries of translation in time and space and rotational symmetry.
- An improved hands-on experience in dealing with important problems of mechanical systems like systems with constraints, normal modes of mechanical vibrations, motion of rigid bodies, etc.
- Demonstrate a deep understanding of how non-relativistic mechanics is generalized to include the theory of relativity.
