QCE PhysicsPractice Examination 6

This paper covers

• Unit 3 Gravity & Electromagnetism: circular motion, Newton's gravitation, Kepler's laws, orbital mechanics, Coulomb's law, electric fields, motor effect, electromagnetic induction (Faraday/Lenz), AC generators, transformers & power transmission
• Unit 4 Revolutions in Modern Physics: special relativity (postulates, simultaneity, time dilation, length contraction, mass-energy), quantum theory (Planck, photoelectric effect, de Broglie, Bohr model), Standard Model (quarks, leptons, baryons/mesons, fundamental forces & bosons, conservation laws, Feynman diagrams)
• Core stimulus: solar-panel photoelectric experiment — UV light of varying frequency on a metal surface, stopping-voltage measurements, Ek-f graph analysis to extract work function W (= 3.32e-19 J, 2.07 eV) and threshold frequency f0 (= 5.0e14 Hz, gradient = h = 6.63e-34 J s)
• QCAA EA format: Paper 1 (Section A 20 MCQ + Section B 28-mark short response) and Paper 2 (Section C 49-mark stimulus/extended response); Assessment Objectives 1-4 only
• Band A standard: full reasoning chains (evidence → physics principle → conclusion), QCAA Formula & Data Book constants, correct SI units, significant figures, and the demanding verbs evaluate/justify/deduce/compare in higher-mark items
