VCE Physics Study Design (Units 3 & 4, 2024–2027)
VCAA sets a single end-of-year examination, listed simply as the Exam for each year from 2017 onwards. Section A is a run of one-mark multiple-choice items sampled across every area of study, including the inquiry skills. Section B holds the bulk of the paper: short-answer and extended-response questions ranging from two-mark explanations up to a large item built around a practical investigation — in 2025 that single question was worth 20 marks. Section B answers are marked on the working and reasoning shown, not only the final value.
Past papers on this subject span more than one study design. Papers written under an older one still work as practice, but the areas of study they test have changed — the index labels every paper with the study design it was set under.

The areas of study, one by one
Each area below lists the concepts named in the study design, what the VCAA exam asks of them, and the mistake that most often costs marks.
Area 1 of 5
How do physicists explain motion in two dimensions?
This area of study takes Newton's laws off the straight line and into two dimensions. You apply them to linear and accelerated motion, to objects on inclined planes, and to uniform circular motion in both the horizontal plane (a car cornering, a banked track) and the vertical plane, where the net force changes relative to weight at the top and bottom of the circle. Projectile motion near Earth's surface is treated by separating independent horizontal and vertical components. The second half is the conservation toolkit: momentum and its conservation in collisions, impulse as the change in momentum and as the area under a force-time graph, and energy transformations between kinetic, elastic potential and gravitational potential energy, including elastic and inelastic collisions where kinetic energy is not conserved.
What the study design lists under this area · 6 points
- Newton's laws applied to linear/accelerated motion
- Uniform circular motion (horizontal and vertical planes)
- Projectile motion near Earth's surface
- Momentum and energy conservation in collisions
- Impulse and momentum in collisions
- Energy transformations (kinetic, elastic, gravitational potential)
What the exam asks
Expect multi-part Section B problems that mix a calculation with a justification: find a fall time and impact speed, then explain what changes if the object is launched horizontally; calculate an impulse, then reason about why an airbag reduces the peak force. Force diagrams, gradient and area readings from graphs, and "show that" verifications of a supplied value are all common.
Where marks go missing
Treating momentum as a scalar — adding speeds instead of signed velocities, or quoting an impulse with no direction. The companion error is assuming kinetic energy is conserved in a collision when only momentum is, which quietly wrecks every later part of the question.

How do things move without contact?
Here you learn to describe action at a distance with field models, and to see what gravitational, electric and magnetic fields have in common and where they differ. You draw and interpret field patterns, apply the inverse square law to the field around a point charge or point mass, and superimpose the fields of two charges vectorially to find the net field, including the point where it cancels. Charged particles are then set moving through fields: accelerated between charged plates in a uniform electric field, and forced into circular paths in a magnetic field. The same physics explains the force on a current-carrying conductor, the operation of DC motors and particle accelerators, and satellites held in orbit by gravity, where the gravitational force supplies the centripetal acceleration.
What the study design lists under this area · 8 points
- Field models: gravitational, electric, magnetic
- Electric fields about point charges (inverse square law)
- Superposition of electric fields from point charges
- Charged particles accelerated in uniform electric fields
- Charged particles in magnetic fields
- Force on current-carrying conductors in magnetic fields
- Satellites and orbital motion in a gravitational field
- Operation of DC motors and particle accelerators
What the exam asks
Section A items test conceptual discrimination — static versus non-uniform fields, field-line patterns, whether gravity does net work over a full orbit. Section B asks you to verify a field strength, add two fields at a point, find the direction of a force with a hand rule, calculate an orbital period or path radius, and explain orbital motion in terms of Newton's laws rather than restating the formula.
Where marks go missing
Mixing up the two field geometries: applying E = V/d to a point charge, or the inverse square law between parallel plates. Direction errors follow close behind — forgetting that an electron's force is opposite to the field, or to the direction a right-hand rule gives.

How are fields used in electricity generation?
This area of study connects the field models to the electricity supply. You start with electromagnetic induction: magnetic flux through a coil, Faraday's law linking induced EMF to the rate of change of that flux, and Lenz's law fixing the direction of the induced current so that it opposes the change producing it. From there you work through the AC generator — how flux through a rotating coil varies, where in the rotation the EMF peaks, and how a commutator changes the output. You then handle alternating voltage and current quantitatively using peak and RMS values, compare AC and DC supplies delivering the same power, and finish with transformers and the transmission problem: stepping voltage up to cut the current, reducing power lost as heat in the transmission lines, then stepping it back down for use.
What the study design lists under this area · 4 points
- Electromagnetic induction (Faraday's/Lenz's law)
- AC generator operation and EMF induction
- AC vs DC voltage and RMS quantities
- Transformers and power transmission
What the exam asks
Typical questions ask you to explain the induced current as a magnet falls through a solenoid and why the entry and exit EMF spikes differ, to verify a flux change and calculate the EMF over a quarter turn, or to work through currents drawn by parallel loads and justify where step-up and step-down transformers belong in a supply chain.
Where marks go missing
Quoting Lenz's law as "it opposes the change" without naming which change, and treating induced EMF as proportional to the flux itself rather than to its rate of change — so a coil sitting in a strong steady field is wrongly said to generate a voltage.

How has understanding about the physical world changed?
This area of study follows two ideas that broke classical physics. The first is the nature of light and matter: interference and diffraction establish light as a wave, then the photoelectric effect and atomic spectra force quantisation, with photon energy set by frequency and the work function setting the threshold. De Broglie's wavelength then runs the argument backwards, since electrons diffract like X-rays of similar wavelength, giving wave-particle duality. The second is special relativity: Einstein's two postulates, what counts as an inertial frame, and the consequences when the speed of light is the same for all observers — time dilation, length contraction measured in the frame that sees the object move, and mass-energy equivalence. Michelson-Morley and the muon are the standard pieces of supporting evidence.
What the study design lists under this area · 6 points
- Light as a wave (interference and diffraction)
- Quantisation of light (photoelectric effect, spectra)
- Wave-particle duality of matter (de Broglie)
- Special relativity postulates and inertial frames
- Length contraction and time dilation
- Mass-energy equivalence
What the exam asks
You will be asked to extract Planck's constant and a work function from a kinetic-energy-versus-frequency graph, to calculate slit separation from a fringe pattern and predict the effect of changing frequency, to find an accelerating voltage for a target de Broglie wavelength, and to compute a contracted length or a relative speed while stating clearly which observer measures what.
Where marks go missing
Assigning proper time or proper length to the wrong observer, so the contraction or dilation is applied backwards. In quantum questions, the parallel slip is arguing from intensity when only frequency determines whether photoelectrons are emitted at all.

Area 5 of 5
How is scientific inquiry used to investigate fields, motion or light?
This is the practical investigation area of study, and it is examinable in its own right rather than being a report of your own experiment. You need to be fluent with the design of an investigation: identifying independent, dependent and controlled variables, choosing a method and equipment that actually isolate the relationship being tested, and recognising the difference between systematic error, which shifts every reading in one direction, and random error, which scatters them. You also need the analysis skills: plotting data with uncertainty bars, drawing a line of best fit, reading a gradient and an intercept and interpreting what each represents physically, linearising a relationship so a curved data set becomes a straight line, and evaluating accuracy, precision and the limitations of a method. Scientific poster conventions for communicating findings are part of the study design.
What the study design lists under this area · 5 points
- Designing and analysing a practical investigation
- Systematic vs random measurement error
- Interpreting experimental data and graphs
- Linearising data for graphical analysis
- Scientific poster communication conventions
What the exam asks
Section A items classify described errors as systematic or random or ask which pair of variables plots as a straight line through the origin. The extended Section B investigation question walks through a whole experiment: naming variables, justifying design decisions, plotting supplied data, finding a gradient, and using that gradient to calculate a physical quantity such as magnetic field strength.
Where marks go missing
Writing "human error" or "the equipment was inaccurate" instead of naming a specific systematic or random effect and stating what it does to the graph — whether it shifts the intercept or scatters points — and therefore what it does to the quantity calculated from the gradient.
