HKDSE Physics study plan

HKDSE Physics · Give each week a clear focus.

8 weeks · About 6 hours per week

Week 1

Mechanics (Physics, Category A Senior Secondary subject)

  • Define and apply the equations of uniformly accelerated motion to solve at least 15 multi-step kinematics problems, including free-fall and projectile cases

  • Draw and interpret displacement–time and velocity–time graphs, and extract acceleration, displacement and average velocity from them

  • Resolve forces into components and apply Newton's three laws to equilibrium and connected-body problems without friction, then with friction

  • State and apply the conditions for equilibrium of a rigid body, taking moments about a chosen pivot

Your checkpoint

A one-page formula-and-method sheet for kinematics and forces, plus a timed 20-question self-test scored and corrected with error notes

Week 2

Mechanics (Physics, Category A Senior Secondary subject)

  • Apply conservation of momentum to collisions and explosions in one dimension, distinguishing elastic from inelastic cases

  • Calculate work, kinetic energy, gravitational potential energy and power, and apply conservation of energy to motion with friction

  • Analyse circular motion problems using centripetal force and identify the force providing it in each case

  • Solve problems involving gravitational force and satellite motion using Newton's law of gravitation

Your checkpoint

A worked portfolio of 10 energy-and-momentum problems, each with a labelled diagram and a stated principle of conservation

Week 3

Heat and Gases (Physics, Category A Senior Secondary subject)

  • Convert between Celsius, Kelvin and absolute pressure units, and apply the ideal gas law to fixed and changing mass problems

  • Distinguish internal energy, heat and temperature, and apply the first law of thermodynamics with correct sign conventions

  • Calculate heat transfer using specific heat capacity and specific latent heat, including mixtures and phase changes

  • Explain pressure in gases using the kinetic theory, and relate molecular speed to temperature

Your checkpoint

A solved set of 12 gas-law and calorimetry problems showing every unit conversion explicitly, self-marked against the marking scheme

Week 4

Heat and Gases (Physics, Category A Senior Secondary subject) & Waves (Physics, Category A Senior Secondary subject)

  • Describe and calculate conduction, convection and radiation heat transfer, and apply the concept of thermal equilibrium

  • Define wave terms (wavelength, frequency, period, amplitude, speed) and apply the wave equation to transverse and longitudinal waves

  • Describe reflection, refraction and total internal reflection, and calculate critical angle and refractive index

  • Draw ray diagrams for lenses and mirrors and locate images using the lens formula

Your checkpoint

A mid-point mock test of 30 mixed mechanics and heat questions under timed conditions, with a scored error log sorted by topic

Week 5

Waves (Physics, Category A Senior Secondary subject)

  • Explain superposition, interference and diffraction, and apply the double-slit and diffraction-grating equations

  • Describe stationary waves on strings and in air columns, and calculate fundamental and harmonic frequencies

  • Relate loudness, pitch and quality of sound to amplitude, frequency and waveform

  • Describe the electromagnetic spectrum and identify applications and hazards of each region

Your checkpoint

A summary table of all wave phenomena with the governing equation, a labelled diagram and one worked example per row

Week 6

Electricity and Magnetism (Physics, Category A Senior Secondary subject)

  • Apply Coulomb's law and electric field concepts to point charges and uniform fields between parallel plates

  • Calculate resistance, current, voltage and power in series and parallel circuits, and apply Ohm's law to non-ohmic conductors

  • Analyse circuits using Kirchhoff's rules and calculate the effect of internal resistance on terminal voltage

  • Describe the magnetic field around a current-carrying conductor and calculate the force on a current in a magnetic field

Your checkpoint

A circuit-analysis worksheet of 10 problems, each solved twice: once by equivalent resistance and once by Kirchhoff's rules

Week 7

Electricity and Magnetism (Physics, Category A Senior Secondary subject) & Radioactivity and Nuclear Energy (Physics, Category A Senior Secondary subject)

  • Explain electromagnetic induction and apply Faraday's law and Lenz's law to predict induced current direction

  • Describe the structure of the atom and the nature of alpha, beta and gamma radiation, including their penetrating power and deflection in fields

  • Apply the radioactive decay law and half-life to calculate activity and remaining nuclei over time

  • Distinguish fission from fusion and calculate mass defect and energy released using E = mc²

Your checkpoint

A decay-and-induction problem set of 12 questions, plus a half-life graph plotted and interpreted in writing

Week 8

Mechanics (Physics, Category A Senior Secondary subject) & Heat and Gases (Physics, Category A Senior Secondary subject) & Waves (Physics, Category A Senior Secondary subject) & Electricity and Magnetism (Physics, Category A Senior Secondary subject) & Radioactivity and Nuclear Energy (Physics, Category A Senior Secondary subject)

  • Consolidate all five domains by reworking every item in the error log until each is solved unaided

  • Complete two full timed papers under exam conditions and allocate time across sections deliberately

  • Identify the three weakest sub-topics from mock results and produce a targeted revision list for each

  • Memorise and rehearse the standard definitions and units that carry marks in written answers

Your checkpoint

Two completed timed mock papers with scores recorded, plus a final one-page revision sheet covering the weakest three sub-topics
