QCE Physics Study Notes Units 3 & 4
Master every QCAA topic in QCE Physics with structured notes, AI flashcards, and mind maps aligned to the current general senior syllabus.
The QCE Physics Units 3 and 4 syllabus moves from gravitational and electromagnetic fields into the modern physics of relativity and the quantum world. These notes break each topic into the equations, derivations and worked-example types that show up on the external assessment, and link to Revizi flashcards for active recall on definitions, units, and constants.
Topic Summaries
Unit 3 Topic 1 — Gravity and Motion
Covers projectile motion, circular motion, orbital mechanics, and Newton's law of universal gravitation. You will calculate orbital periods using Kepler's third law and analyse satellite motion in gravitational fields.
Unit 3 Topic 2 — Electromagnetism
Examines magnetic fields, the motor effect, electromagnetic induction, Lenz's law, and the operation of generators and transformers. Includes power transmission and the I²R loss argument for high-voltage networks.
Unit 4 Topic 1 — Special Relativity
Explores Einstein's postulates, time dilation, length contraction, and relativistic momentum and energy. You will apply the Lorentz factor to high-speed scenarios and interpret the muon decay evidence for relativistic effects.
Unit 4 Topic 2 — Quantum Physics
Focuses on the photoelectric effect, wave-particle duality, the Bohr model, and emission and absorption spectra. Includes de Broglie wavelengths and an introduction to the Standard Model of particle physics.
How to Study Effectively
Physics rewards a small set of equations applied fluently across many contexts. Read each topic summary for the conceptual model, then use Revizi flashcards to memorise the equation forms, units, and definitions you need at exam speed. Spaced repetition makes the high-frequency recall items — Lorentz factor, Lenz's law sign convention, photoelectric work function — second nature for the external assessment.

Frequently Asked Questions
What topics do QCE Physics Units 3 & 4 study notes cover?
These notes cover gravity and motion (Unit 3 Topic 1), electromagnetism (Unit 3 Topic 2), special relativity (Unit 4 Topic 1), and quantum physics (Unit 4 Topic 2). Each summary is mapped to the current QCAA general senior syllabus.
How do these notes prepare me for the QCAA external assessment?
Each topic summary highlights the equation derivations, calculation patterns, and conceptual explanations that have appeared on QCAA past papers. Combined with Revizi flashcards for active recall, they cover both the qualitative and quantitative skills the EA tests.
Do the notes include the QCAA Physics data sheet?
We reference the data sheet conventions and constants throughout so you do not have to memorise every value. The notes train you to recognise which data-sheet relationship applies to each problem type.
Are the notes aligned to the latest QCAA syllabus?
Yes. They are mapped to the current QCE Physics general senior syllabus and are reviewed when QCAA updates the syllabus.
Are Revizi’s QCE Physics study notes free?
Yes. All QCE Physics Units 3 & 4 study notes on this page are free, no account needed. When you do sign in (also free), you can generate AI flashcards from your own uploaded notes aligned to the QCAA syllabus, plus mind maps; Pro just raises the daily generation ceiling.
