Learning Outcomes
Module Content
  • More on Momentum and Energy (flow of mass: dynamics of systems with varying mass, elastic and inelastic collisions, centre of mass frame);


  • Some mathematical aspects (gradient, Stokes' theorem);


  • More on angular momentum (fixed axis of rotation, motion combining translation and rotation);


  • Rigid body motion (angular velocity and angular momentum as vectors, the gyroscope, precession);


  • Gravity (historical background: from Brahe and Kepler to Newton and from Newton to Einstein, Newton's law of gravitation, inertial and gravitational mass, experimental tests, limits of validity, applications: elementary systems, astronomical and astrophysical systems);


  • Central forces (two-body problem, reduced mass, general properties of central force motion);


  • Non-inertial frames and fictitious forces (accelerating non-rotating frames, rotating coordinate systems, centrifugal and Coriolis forces, tidal forces, rotating bucket and Mach's principle, the equivalence principle and origins of General Relativity, Galilean transformations, principle of Relativity);


  • Elements of fluid dynamics.
