VCE Physics: complete 2026 guide to Units 1, 2, 3 and 4 (2023-2027 study design)
A complete 2026 guide to VCE Physics Units 1, 2, 3 and 4 under the 2023-2027 VCAA study design. The four units, the areas of study, the SAC and exam structure, scaling, and links to every dot-point answer we have for VCE Physics.
VCE Physics covers four units across Years 11 and 12, sat under the VCAA 2023-2027 study design. Units 1 and 2 set up thermodynamics, electricity, nuclear physics and motion in one dimension. Units 3 and 4 (the Year 12 sequence) build the fields framework, electromagnetic induction, waves, light and special relativity, and produce a VCE study score.
This page is the index. Below you will find every dot-point answer we have for VCE Physics in 2026, organised by unit and area of study, alongside the structural notes you need to plan study.
The four VCE Physics units in 2026
Unit 1: How is energy useful to society? Thermodynamics, heat transfer and climate; electric circuits (Ohm's law, series and parallel, power, household electricity); nuclear physics and radioactivity. Assessed at S/N level only.
Unit 2: How does physics help us to understand the world? Motion in one dimension (kinematics, Newton's laws, momentum, energy) plus a student-chosen option topic (for example astrophysics, sound, sport science). Assessed at S/N level only.
Unit 3: How do fields explain motion and electricity? Newtonian motion in two dimensions (projectiles, circular motion, momentum and impulse); gravitational, electric and magnetic fields; DC motors, electromagnetic induction, AC and DC generators, transformers and power transmission. Two SACs and exam.
Unit 4: How have creative ideas and investigation revolutionised thinking in physics? Mechanical and electromagnetic waves, interference and diffraction; the photoelectric effect and the wave-particle nature of light; Einstein's special relativity (time dilation, length contraction, mass-energy equivalence); and the Unit 4 student-designed scientific investigation.

Exam structure (Units 3 and 4)
The VCE Physics exam is a single paper.
- Duration: 2 hours 30 minutes plus 15 minutes reading time.
- Total marks: 130.
- Section A: about 20 multiple-choice questions for 20 marks.
- Section B: short-answer and extended-response questions for about 110 marks, including data analysis, graph sketching and several extended-response items worth 6 to 10 marks each.
Both Units 3 and 4 are examined. About half the marks test Unit 3 content (fields, motion in two dimensions, electromagnetic induction) and half test Unit 4 content (waves, light, special relativity), with some questions integrating across units.
How VCE Physics scales
VCE Physics typically scales up by 3 to 4 points. A study score of 30 commonly scales to around 33-34; a study score of 40 to around 43-44; a study score of 45 to around 48. Physics scales above Biology because of its smaller, more mathematical cohort. For ATAR planning, run scenarios in the VCE ATAR calculator.

- Induced EMF calculator for Faraday's law.
- Transformer calculator for turns ratios and power transmission losses.
Study strategy by unit
Units 1 and 2. Build your equation-handling base. Aim for one summary sheet per area of study with the equations, the units, and one fully worked numerical example. SACs reward careful unit conversion and explicit working.
Unit 3. This is the equation-heavy unit. Build a single A3 sheet of the field equations (, , , , ) and drill them across past papers. Use our Unit 3 dot-point pages as your active recall checklist.
Unit 4. This is more conceptual. Waves and the photoelectric effect reward clean graphs and explicit links between gradient or intercept and physical quantities. Special relativity rewards careful frame-of-reference language and unit-by-unit substitution into the time-dilation and length-contraction equations.
The system around VCE Physics
VCE Physics sits inside the wider VCE system. Related explainers:
- How the VCE ATAR is calculated covers VTAC's aggregate and scaling mechanics.
- How VCE study scores work explains the 0-50 scale and per-subject scaling offsets.
- SACs and SATs explained covers internal assessment and moderation.
- VCE exam day: what to actually expect covers logistics and timing.
How to use this hub
If you are starting Unit 3: work through AoS 1 in study-design order (Newton's laws and momentum first, then projectiles, then circular motion and banking). Move to AoS 2 once you can resolve forces and apply cleanly. AoS 3 builds on AoS 2 and needs Faraday's law to be second nature.
If you are sitting the exam in three weeks: drill multiple choice from the last five years of past papers, write one full timed extended response per area of study, and re-read our VCE exam day guide. Polish what you have; do not start new content.

Common questions about Physics
- VCE Physics runs across four units. Unit 1 (How is energy useful to society?) covers thermodynamics, electricity and nuclear physics. Unit 2 (How does physics help us to understand the world?) covers motion in one dimension plus an option topic. Unit 3 (How do fields explain motion and electricity?) covers Newtonian mechanics in two dimensions, gravitational, electric and magnetic fields, and electromagnetic induction including generators and transformers. Unit 4 (How have creative ideas and investigation revolutionised thinking in physics?) covers waves, the photoelectric effect, special relativity and the student investigation. Units 3 and 4 are the Year 12 sequence and produce a study score.
- The VCE Physics exam is sat in November as part of the VCAA written exam timetable. It is a single 2.5-hour paper plus 15 minutes reading time covering Units 3 and 4. Section A is about 20 multiple-choice questions (20 marks) and Section B is short-answer and extended-response questions for about 110 marks, including data analysis. Check the current VCAA exam timetable for the exact date.
- Your VCE Physics study score is calibrated to a mean of 30 and SD of 7. Around 40 percent comes from your two Unit 3-4 School-Assessed Coursework (SAC) tasks and around 60 percent from the end-of-year exam. SACs are statistically moderated against your school's exam performance. Units 1 and 2 are satisfactory or non-satisfactory only and do not directly contribute to the study score, but they build the mechanics and electricity foundations for Units 3 and 4.
- The 2023-2027 study design (replacing the 2017-2022 design) restructured Unit 3 around fields. Newtonian motion in two dimensions (projectiles, circular motion, momentum and energy) was paired with gravitational, electric and magnetic fields and with electromagnetic induction. Unit 4 keeps waves, photoelectric effect and special relativity but reorganises the wave-particle nature of light content. Key science skills are now consistent across all four units, including a stronger role for the student-designed scientific investigation in Unit 4.
- VCE Physics typically scales up by a few points because the cohort is smaller and more mathematically prepared. A raw study score of 30 commonly scales to about 33-34, and a raw 40 to about 43-44. Physics is one of the better-scaling sciences, especially when taken with Specialist Mathematics. For exact scaling each year, check the VTAC scaling report.
- In Units 3 and 4 you complete School-Assessed Coursework (SAC) tasks for each area of study. SAC formats include practical investigation reports, data analysis tasks, structured questions and modelling tasks. The Unit 4 student-designed scientific investigation (AoS 3) is a major SAC, often presented as a scientific poster. SACs are designed by your school but moderated against the exam.
- Split the motion into horizontal (constant velocity) and vertical (constant acceleration due to gravity). Use t as the shared variable across both axes.
- Work (J) is energy transferred by a force over a distance. Power (W) is the rate of doing work β work divided by time.
- In any collision (elastic or inelastic) where no external net force acts on the system. Kinetic energy is only conserved in elastic collisions.
- Light shone on a metal can eject electrons, but only if the photon energy (hf) exceeds the work function. The kinetic energy of the ejected electron is hf - W. Evidence that light behaves as discrete quanta (photons).
- F = BIL sin ΞΈ for a wire in a uniform field B with current I and length L. Direction comes from the right-hand rule. Underpins motors, generators, and ammeters.
