Central potential and conservation of energy and angular momentum; effective potential, Kepler's laws (planetary motion), satellite orbits.
Key theme: Symmetry and conservation laws

** Unit 4: The Equation of Continuity **

The concepts of flux and divergence of a force field; Gauss' theorem, equation of continuity and its physical meaning; Local description of conservation of mass and charge.
Key theme: Physical significance of the equation of continuity and its universality.
