|Not being delivered|
On completion of this course, the student will be able to:
- State the basic principles of classical dynamics, special relativity and elementary quantum mechanics and the regimes in which the different theories apply.
- Apply these principles in conjunction with elementary mathematical techniques to solve simple problems in classical, relativistic and quantum mechanics.
- Present a solution to a physics problem in a clear and logical written form.
- Assess whether a solution to a given problem is physically reasonable.
- Locate and use additional sources of information (to include discussion with peers where appropriate) to facilitate independent problem-solving.
