I've decided to concentrate on physics for the time being...

Syllabus:

Syllabus of APhO
A. Theoretical Part
1) Mechanics
Foundation of kinematics of a point mass
Vector description of the position of the point mass velocity and acceleration as vectors
Newton's laws, inertial systems
Problems may be set on changing mass
Closed and open systems, momentum and energy, work, power
Conservation of energy, conservation of linear momentum, impulse
Elastic forces, frictional forces, the law of gravitation, potential energy and work in a gravitational field
Hooke's law, coefficient of friction (F/R=const), frictional forces static and kinetic, choice of zero of potential energy
Centripetal acceleration, Kepler's law

2) Mechanics of Rigid Bodies
Statics, center of mass, torque
Couples, conditions of equilibrium of bodies
Motion of rigid bodies, translation, rotation, angular velocity, angular acceleration, conservation of angular momentum
Conservation of angular momentum about fixed axis only
External and internal forces, equation of motion of a rigid body around the fixed axis, moment of inertia, kinetic energy of a rotating body
Parallel axes theorem (Steiner's theorem), additivity of the moment of inertia
Accelerated reference systems, inertial forces
Knowledge of the Coriolis force formula is not required

3) Hydromechanics
No specific questions will be set on this but students would be expected to know the elementary concepts of pressure, buoyancy and the continuity law.

4) Thermodynamics and Molecular Physics
Internal energy, work and heat, first and second laws of thermodynamics
Thermal equilibrium, quantities depending on state and quantities depending on process
Model of a perfect gas, pressure and molecular kinetic energy, Avogadro's number, equation of state of a perfect gas, absolute temperature
Also molecular approach to such simple phenomena in liquids and solids as boiling, melting etc.
Work done by an expanding gas limited to isothermal and adiabatic processes
Proof of the equation of the adiabatic process is not required
The Carnot cycle, thermodynamic efficiency, reversible and irreversible processes, entropy (statistical approach), Boltzmann factor
Entropy as a path independent fiction, entropy changes and reversibility, quasistatic processes

Superposition of harmonic waves, coherent waves, interference, beats, standing waves
Realisation that intensity of wave is proportional to the square of its amplitude. Fourier analysis is not required but candidates should have some understanding that complex waves can be made from addition of simple sinusoidal waves of different frequencies. Interference due to thin films and other simple systems (final formulae are not required), superposition of waves from secondary sources (diffraction)
