AQA GCSE Physics Specification: The Complete Topic-by-Topic Guide

The AQA GCSE Physics specification (8463) is built around eight topic areas: energy, electricity, particle model of matter, atomic structure, forces, waves, magnetism and electromagnetism, and space physics (the last one only for students taking separate Physics, not Combined Science). These eight topics are split evenly across two exam papers, are supported by ten required practicals, and together they define everything you need to revise for your GCSE Physics exams. This guide breaks down exactly what's in each topic, how the papers are structured, and how to build a revision plan that actually covers the whole specification.

The Eight Topic Areas at a Glance

AQA groups the Physics content into eight numbered topics. If you're taking Combined Science: Trilogy, you'll cover topics 1 to 7 in slightly reduced depth across two Physics papers within your combined award. If you're taking separate GCSE Physics, you'll study all eight topics, including the additional space physics content and some extra depth in the other areas.

• Energy — energy stores and transfers, efficiency, specific heat capacity, power, and energy resources
• Electricity — circuits, current, potential difference, resistance, series and parallel circuits, and mains electricity
• Particle model of matter — density, changes of state, internal energy, specific latent heat, and particle motion in gases
• Atomic structure — the structure of the atom, radioactive decay, half-life, nuclear radiation, and its uses and hazards
• Forces — scalar and vector quantities, contact and non-contact forces, resultant forces, Newton's laws, momentum, and stopping distances
• Waves — transverse and longitudinal waves, wave properties, the electromagnetic spectrum, and reflection and refraction
• Magnetism and electromagnetism — permanent and induced magnets, magnetic fields, the motor effect, and the generator effect
• Space physics (Physics only) — the solar system, life cycles of stars, orbital motion, and red-shift

Each topic contains several sub-topics, and AQA's official subject content document lists every individual learning point in detail — it's worth checking against the specification itself if you want to be completely thorough, since exact wording is occasionally refined between exam series.

How the Topics Map to Paper 1 and Paper 2

GCSE Physics is a linear qualification, which means everything is assessed in two exams sat at the end of Year 11 — there's no coursework and no early modules to bank. Each paper lasts 1 hour 45 minutes and is worth 100 marks, split roughly 62% multiple choice and short answer, with the rest given over to extended response and calculation questions.

• Paper 1 covers energy, electricity, particle model of matter, and atomic structure
• Paper 2 covers forces, waves, magnetism and electromagnetism, and space physics

Both papers include required practical questions, maths skills questions (physics has the heaviest maths content of the three sciences, at around 30% of total marks), and synoptic questions that pull together ideas from more than one topic. A common mistake is treating Paper 1 and Paper 2 as separate subjects to revise in isolation — in reality, energy calculations show up inside forces questions, and wave equations reappear in electromagnetism, so cross-topic practice matters as much as topic-by-topic recall.

The Ten Required Practicals

AQA specifies ten required practical activities that you must have carried out during the course. You won't be examined on lab technique alone, but expect exam questions on the method, apparatus, variables, sources of error, and how to interpret the results — these questions appear across both papers and typically carry significant marks.

• Determining densities of regular and irregular objects
• Investigating thermal insulation (separate Physics only)
• Investigating specific heat capacity
• Resistance of a wire, and combinations of resistors
• Investigating I–V characteristics of circuit components
• Investigating forces and extension of a spring
• Investigating the acceleration of an object
• Investigating waves on a string and in water
• Investigating light reflection and refraction (separate Physics only)
• Investigating the emission and absorption of infrared radiation

Since two of these are physics-only, Combined Science students should double-check with their teacher exactly which eight apply to their course. For every practical, learn the independent, dependent, and control variables, and be ready to sketch or describe the apparatus from memory.

A Systematic Revision Approach

Trying to revise GCSE Physics topic-by-topic in whatever order feels comfortable is one of the biggest reasons students end up with patchy knowledge. A more reliable approach follows the structure of the specification itself:

1. Map the eight topics against past paper questions so you know which areas come up most often and which ones you're weakest on
2. Revise Paper 1 topics together — energy, electricity, particle model, and atomic structure share a lot of equations and units, so learning them as a block reinforces recall
3. Practise the required practicals separately from content revision, since practical-based questions test understanding of method rather than facts
4. Interleave maths-heavy questions throughout your revision rather than leaving them until the end — physics calculations need repetition to become fluent
5. Sit full past papers under timed conditions in the final weeks, marking strictly against the AQA mark scheme so you get used to how marks are actually awarded

Equation recall is worth particular attention. AQA gives you some equations on an equation sheet in the exam, but a smaller set has to be memorised, so it's worth knowing early on which is which rather than discovering the gap in the exam hall.

How Applaa's AI Tutor Helps You Track Progress

Working through all eight topics, ten practicals, and two papers by hand is a lot to keep organised, which is where Applaa is genuinely useful rather than just another revision app. Applaa's free AI tutor is mapped to the AQA GCSE Physics specification, so when you practise questions on, say, electromagnetism, it knows exactly which sub-topic and paper that content belongs to, and it flags the areas you haven't touched yet.

Instead of guessing where your gaps are, you get a live progress view across all eight topics, broken down by Paper 1 and Paper 2, so you can see at a glance whether you're neglecting space physics in favour of easier topics like energy. Applaa also generates practice questions in the same style as AQA past papers, gives instant feedback with mark-scheme-style explanations, and adapts future questions based on where you're actually struggling — rather than making you repeat topics you've already mastered.

If you're starting your GCSE Physics revision and want a clearer picture of where you stand across the whole specification, try a free session with Applaa's AI tutor and let it build a topic-by-topic progress map for you as you go.
