QCE PhysicsPractice Examination 19

This paper covers

• Unit 3 Gravity and Electromagnetism: uniform circular motion and centripetal force, Newton's Law of Universal Gravitation and gravitational field strength, Kepler's three laws and orbital/satellite mechanics, Coulomb's Law and electric fields, work done on charges, the motor effect (F=BIL and F=qvB), electromagnetic induction via Faraday's and Lenz's Laws, AC generators, and transformer operation applied to power transmission
• Unit 4 Revolutions in Modern Physics: special relativity (two postulates, simultaneity, time dilation, length contraction, mass-energy equivalence), quantum theory (Planck's hypothesis, photoelectric effect, de Broglie duality, Bohr hydrogen model), and the Standard Model (quarks, leptons, baryons/mesons, antiparticles, four fundamental forces and exchange bosons, conservation laws, Feynman diagrams)
• Stimulus context: a 330 kV to 240 V outback substation transformer (turns ratios, Lenz's Law in coil operation, current ratios at 100% efficiency) plus power-transmission loss analysis
• Assessment Objectives 1-4 only (describe/explain, apply, analyse evidence, interpret evidence) with the full evidence-to-principle-to-conclusion reasoning chain demanded by Band A, across Paper 1 (Section A 20 MCQ + Section B 28 marks) and Paper 2 (Section C 49 marks), total 97 marks
