GCSE Physics is examined entirely through two written papers sat at the end of Year 11. There is no coursework or portfolio. Students also complete eight required practicals during the course, and the skills developed through these experiments are assessed through questions in both papers. Physics is the most mathematically demanding of the three separate sciences.
How many papers does GCSE Physics have?
Under the AQA specification, GCSE Physics consists of two written papers, each lasting one hour and forty-five minutes and worth 100 marks. All students entered for triple (separate) Physics sit the same two papers. The two papers together form the full qualification.
The table below shows the overall structure:
| Paper | Topics covered | Duration | Marks |
|---|---|---|---|
| Paper 1 | Energy, Electricity, Particle Model of Matter, Atomic Structure | 1 hr 45 min | 100 |
| Paper 2 | Forces, Waves, Magnetism and Electromagnetism, Space Physics | 1 hr 45 min | 100 |
Both papers include multiple-choice questions, structured questions requiring short answers, and extended-response questions requiring explanation or calculation. A significant proportion of marks in each paper require mathematical working.
What topics appear in GCSE Physics Paper 1?
Paper 1 covers four topic areas:
Energy — energy stores and transfers (kinetic, gravitational potential, elastic potential, thermal), conservation of energy, calculating efficiency, power (the rate of energy transfer), and how national and global patterns of energy use are changing. Students are expected to substitute values into equations, including for kinetic energy (½mv²) and gravitational potential energy (mgh).
Electricity — electric charge, current, potential difference and resistance, Ohm's Law and I-V characteristics, series and parallel circuits, the domestic mains supply (live/neutral/earth wires, fuses, circuit breakers), the National Grid, and static electricity. This topic includes a high density of equations and calculation questions.
Particle Model of Matter — states of matter and changes of state, density, specific heat capacity, specific latent heat (the energy required to change state without changing temperature), and pressure in gases (including the relationship between pressure, volume, and temperature for a fixed mass of gas).
Atomic Structure — the history of atomic models, the structure of the nucleus, isotopes, radioactive decay (alpha, beta, and gamma radiation), uses of nuclear radiation, nuclear fission and fusion, and the background radiation in everyday life.
What topics appear in GCSE Physics Paper 2?
Paper 2 covers the remaining four topic areas:
Forces — scalar and vector quantities, contact and non-contact forces, gravity, elasticity (Hooke's Law), distance-time and velocity-time graphs, Newton's three laws of motion, momentum (conservation of momentum), stopping distance in road safety contexts, and terminal velocity.
Waves — transverse and longitudinal waves, wave speed, frequency and wavelength (including the wave equation), the electromagnetic spectrum (properties and uses of each region from radio waves to gamma rays), reflection, refraction, sound waves, and required practical work on wave speed in strings and ripple tanks.
Magnetism and Electromagnetism — magnets and magnetic fields, the motor effect, electromagnetic induction, the generator effect, transformers (including the equation linking turns ratio to voltage), and practical applications such as electric motors and generators.
Space Physics — the Solar System, orbital motion, the life cycle of stars (from nebula to white dwarf, neutron star, or black hole), the Big Bang theory, and red shift as evidence for an expanding universe. Some content in this topic is Higher Tier only.
What are the required practicals?
All GCSE Physics students must complete eight specified required practicals during Years 10 and 11. These are not submitted for marking, but questions about their methodology, data analysis, and evaluation appear regularly in both papers. The eight AQA required practicals include:
- Investigating the specific heat capacity of a material
- Investigating the resistance of wires of different lengths
- Plotting I-V characteristics for a resistor, filament lamp, and diode
- Investigating the density of objects
- Investigating the extension and force in a spring (Hooke's Law)
- Investigating the speed of waves in a string (using a vibration generator)
- Investigating the refraction of light using glass blocks and ray boxes
- Investigating the absorption and emission of infrared radiation
How is GCSE Physics graded?
Triple GCSE Physics is graded 9–1, with 9 the highest. Students studying the three separate sciences each receive an individual grade. Students on Combined Science: Trilogy receive a double grade (such as 6-5) covering all three sciences, counting as two GCSEs.
Physics has the highest mathematical demand of the three sciences at GCSE. Students must recall and apply equations from memory in the exam — the AQA specification requires students to know a set list of equations and also provides a separate set in the exam paper. Understanding which equations must be memorised and which will be provided is an important part of revision.
How can parents support GCSE Physics revision?
Physics rewards systematic practice with calculations more than most subjects. Useful strategies include:
- Practising equation questions repeatedly — particularly compound calculations that involve rearranging equations (e.g., calculating current when given power and voltage)
- Drawing and interpreting graphs — velocity-time graphs, I-V characteristic curves, and wave diagrams appear almost every year
- Working through required practical scenarios — knowing what a ripple tank measures and how to reduce experimental error is regularly examined
- Making a list of all equations — annotating the equation sheet with examples of when each equation is used
Frequently asked questions
Is GCSE Physics mostly maths?
It has a higher mathematical content than Biology and Chemistry, but it is not exclusively calculation-based. Descriptive and explanatory questions — explaining how a transformer works, describing the life cycle of a star, or evaluating a safety feature — are worth a significant proportion of marks. Students who avoid the calculations and focus only on descriptive content will still struggle to reach grades 7, 8, or 9.
Does my child need to memorise all the Physics equations?
Under AQA, some equations are provided on an equation sheet given in the exam; others must be recalled from memory. The specification clearly lists which equations fall into each category. Students should learn the "must be recalled" list in Year 10 and spend Year 11 practising applying all equations under timed conditions, because under exam pressure, even provided equations require practice to use quickly.
What is Higher Tier-only content in Physics?
Certain topics or aspects of topics are designated Higher Tier only — they are only assessed in papers entered at the Higher level and are not examined in the Foundation tier of combined science. In AQA Physics, Higher-only content includes topics such as the equation for momentum (mv), some aspects of Space Physics, the transformer equation, and aspects of electric field strength. Schools following the triple science pathway enter students at Higher Tier.
Which A-level subjects require a good GCSE Physics grade?
A-level Physics and A-level Engineering typically require grade 6 or above at GCSE Physics. A-level Mathematics students with a Physics GCSE often find the mechanics modules more approachable. Medicine and dentistry do not specifically require Physics at GCSE, but for students considering Engineering, Architecture, or Physics at university, a strong GCSE Physics result is very useful for sixth form entry.
