Learning Outcomes

Students who successfully complete this paper will be able to:

  • State Newton's laws and apply them to developing equations of motions in different situations
  • Solve classical mechanics problems using appropriate choices of coordinates and integration techniques
  • Understand and apply the energy formalism to single and multiple particle motion, ulilizing conservative forces where appropriate
  • State the time-dependent Schrödinger equation, understand how to obtain its time-independent form, and stationary states
  • Calculate properties of simple one-dimensional quantum systems
  • Understand the extension of quantum theory to three-dimensional systems and the stationary states of the hydrogen atom
  • Present written, logical and clear solutions to problems in classical mechanics and quantum mechanics
  • Work together in groups on problem solving activities
