QCE PhysicsPractice Examination 16

This paper covers

• Unit 3 Gravity & Electromagnetism: Coulomb's Law, electric fields, work on charges, Newton's law of gravitation, gravitational field strength, Kepler's laws, orbital/satellite motion, uniform circular motion, motor effect, magnetic force on charges/conductors, Faraday's & Lenz's Laws, 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, fundamental forces & exchange bosons, conservation laws, Feynman diagrams)
• Stimulus context: a charged sphere rolled on a frictionless horizontal surface near a second charged sphere — applying Coulomb's Law, comparing the electric force to gravity between the same masses, and locating the equilibrium separation
• Assessment Objectives 1-4 only (describe/explain, apply, analyse, interpret); Band A reasoning chains (evidence cited → physics principle → justified conclusion) on evaluate/justify/deduce/compare items; correct QCAA Formula & Data Book formulae, SI units and significant figures throughout
