  1. Effective Study • Review the material (mind map) • Talk physics (flash cards, focus on key ideas) • Practise Questions (workbook or Exam) • Mark and correct (make notes) • Timing:

  2. Conservation of momentum in 2 dimensions Reference circle & phasors (tides) Forced SHM and resonance Conservation of energy Centre of Mass Oscillating motion, y, v, a Time and frequency Simple Harmonic Motion Revision of kinematics Translational motion Conservation Rotational kinetic energy Mechanics Banked corners Angular Momentum Circular motion Rotational motion Rotational Inertia Vertical forces (swinging bucket) Centripetal force & centripetal acceleration Angular kinematic equations, θ, ω, α Torque Gravitation Satellite motion

  3. Young’s double slit experiment All EM waves and sound Multi-slit interference & diffraction gratings Doppler Effect Interference Waves Standing Waves - Music Harmonics and Overtones Superposition Strings Open pipe Closed pipe Beat frequency

  4. Wave-particle duality Quantisation of Energy (PHOTON) Bohr’s Atomic Model (energy levels) The electron volt 1 eV = 1.6x10-19 J The Photoelectric Effect E = mc2 Discrete energy levels Atomic Nuclear Binding Energy & Mass Deficit Electron transition Atomic line spectra Conservation of mass-energy for nuclear fusion and fission Ionisation (electron freed from atom) Hydrogen Visible – Balmer (n=2) Ultraviolet – Lyman (n=1) Infrared – Paschen(n=3)

  5. Resonance in LRC circuits Charging & discharging graphs Phase relationships Time constant (L/R), τ, Reactance & Impedance Internal Resistance, r Peak & RMS V/I Kirchoff’s Laws -Current junction -Voltage sum=0 Mutual Inductance (transformers) LR Circuits AC Circuits Self inductance DC Circuits Energy in inductors Inductance, M/L, Henrys Electricity Capacitance, C, Farads Electromagnetic Induction Charging & Discharging graphs Parallel plate capacitors Magnetic flux, φ Capacitors in series and parallel RC Circuits Dielectrics Magnetic flux density, B Energy stored in a capacitor Lenz’s Law Time constant, τ, RC Faraday’s Law
