HKDSE Physics study guide
HKDSE Physics · Work through your exam, one topic at a time.
HKDSE Physics is a Category A Senior Secondary elective in the Hong Kong Diploma of Secondary Education, administered by the Hong Kong Examinations and Assessment Authority (HKEAA). It is taken by Secondary 6 candidates in Hong Kong schools, and by private candidates, who need a physics result for university admission, especially for engineering, physical sciences, and health-related programmes. The HKDSE Physics study guide has 5 sections and about 1,959 words.
01Mechanics
Mechanics is the HKDSE Physics domain that tests how you describe motion, identify forces, and apply conservation laws to particles and simple systems. Questions often combine a graph, a free-body diagram, or a multi-stage motion, so the examiner is checking whether you can choose the right principle rather than just substitute numbers.
405 words, about 2 min02Heat and Gases
Heat and Gases tests your understanding of temperature, internal energy, heat transfer, and the macroscopic and molecular behaviour of gases. HKDSE questions commonly combine specific heat capacity, latent heat, and gas-law calculations, or ask you to explain pressure and temperature using kinetic theory.
395 words, about 2 min03Waves
Waves tests how energy and information travel without bulk matter moving with the wave. HKDSE questions cover wave properties, reflection, refraction, diffraction, interference, stationary waves, sound, and the electromagnetic spectrum; you are expected to connect a wave graph or experimental set-up to the wave equation and to path-difference reasoning.
385 words, about 2 min04Electricity and Magnetism
Electricity and Magnetism tests circuit analysis, electrical power, electrostatic forces, magnetic fields, and electromagnetic induction. HKDSE questions often require you to combine Ohm’s law with series and parallel rules, interpret a graph of p.d.
400 words, about 2 min05Radioactivity and Nuclear Energy
Radioactivity and Nuclear Energy tests the random nature of radioactive decay, the properties and hazards of radiation, decay equations, half-life, and the energy released in nuclear fission and fusion. HKDSE questions often ask you to use half-life graphically or numerically, balance a nuclear equation, and explain why mass defect appears as energy.
