QCE PhysicsPractice Examination 3

This paper covers

• Unit 3 Gravity & Electromagnetism: uniform circular motion, Newton's gravitation, gravitational field strength, Kepler's laws, orbital/satellite mechanics, Coulomb's Law, electric fields, work on charges, 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 equivalence), quantum theory (Planck, photoelectric effect, de Broglie duality, Bohr hydrogen model), Standard Model (quarks, leptons, baryons, mesons, antiparticles, four forces & exchange bosons, conservation laws, Feynman diagrams)
• Stimulus thread: a charged oil droplet suspended motionless between parallel plates (Millikan-style) - calculating electric field strength E=V/d, charge q from force balance qE=mg, number of excess electrons, and work done W=qV moving the droplet between plates
• Assessment Objectives 1-4 only: describe/explain, apply/calculate, analyse evidence, interpret & justify - with higher-mark items using evaluate, justify, deduce and compare
• Band A standard: correct QCAA Formula & Data Book formula stated, full substitution with units, step-by-step algebra, final answer with correct SI unit and significant figures; full evidence to principle to conclusion reasoning chains
