A complete guide to Edexcel A-Level Physics
Edexcel A-Level Physics (specification 9PH0, awarded by Pearson) is one of the three major UK A-Level physics routes. It is a linear two-year course assessed across three written papers at the end of Year 13, plus a Pass/Fail practical endorsement run by your teachers. The qualification is built around 13 topics, with a slightly more applied flavour than AQA or OCR – more emphasis on context and on quantitative analysis of real-world data.
This guide covers how each paper is structured, what content is on each, how the 16 core practicals appear in the exam, and the revision techniques that genuinely lift Edexcel physics grades.
Three papers, 13 topics
Paper 1 (Advanced physics I) and Paper 2 (Advanced physics II) test defined topic ranges. Paper 3 (General and practical principles) is synoptic and includes a heavy practical focus.
16 core practicals
Edexcel specifies 16 core practicals across the two-year course. Practical questions appear across all three papers, with the highest concentration on Paper 3.
40% maths content
Ofqual mandates that at least 40% of A-Level physics marks test mathematical skills. Edexcel papers often sit slightly above this, especially in extended response questions.
How Edexcel A-Level Physics is assessed
Edexcel A-Level Physics is a linear qualification: All three papers are sat at the end of Year 13 in the May/June exam series. There is no coursework that contributes to your grade, although the science practical endorsement runs alongside the exams.
The three papers split the spec into two content-led papers and one synoptic, practical-led paper. Together they test recall, application to unfamiliar contexts, and analysis of practical and quantitative data.
| Paper | Content covered | Length | Marks | Weighting |
|---|---|---|---|---|
| Paper 1: Advanced physics I | Topics 1–6 and the core practicals associated with them | 1h 45m | 90 | 30% |
| Paper 2: Advanced physics II | Topics 7–13 and the core practicals associated with them | 1h 45m | 90 | 30% |
| Paper 3: General and practical principles in physics | Synoptic content from across the whole spec, with a focus on practical techniques and data analysis | 2h 30m | 120 | 40% |
Each paper mixes short structured questions, longer extended responses, and a high proportion of calculation questions. Paper 3 is the biggest single paper in the qualification at 2h 30m and 120 marks, and it is the paper where students who under-prepare on practicals or synoptic links lose grades.
AS and full A-Level Edexcel offers a standalone AS Physics qualification (8PH0) covering only the Year 12 topics, assessed in two 1.5-hour papers. AS marks do not carry forward to the full A-Level: It is a separate qualification. This guide covers the full A-Level (9PH0).
Paper 1 in detail
Paper 1 (Advanced physics I) covers topics 1 to 6 of the specification, drawing on mechanics, materials, waves, and the particle nature of light. It is the foundation paper and the calculations are the most direct of the three papers.
Topic 1: Working as a physicist
Physical quantities and SI units, scientific method, uncertainty, and how physics is communicated. This topic runs through every other topic and is heavily tested on Paper 3.
Topic 2: Mechanics
Motion (equations of motion, projectile motion, scalars and vectors), forces and Newton's laws, work, energy and power, momentum and conservation, terminal velocity.
Topic 3: Electric circuits
Charge and current, potential difference, resistance, IV characteristics, resistivity, EMF, internal resistance, series and parallel circuits, the potential divider.
Topic 4: Materials
Density, viscosity (a distinctive Edexcel feature), Hooke's law, Young's modulus, stress and strain, the stress-strain graph, breaking stress, and the behaviour of materials under load.
Topics 5 and 6: Waves and particle nature of light
Progressive and stationary waves, the wave equation, superposition and interference, Young's slits, single slit diffraction, diffraction gratings, refraction and total internal reflection, polarisation, the photoelectric effect, line spectra and energy levels, wave-particle duality.
Exam tip for Paper 1 Edexcel's materials topic includes viscosity – a content area that AQA and OCR cover less deeply. Make sure you can describe Stokes's law for a sphere falling through a viscous fluid, terminal velocity for a falling ball bearing, and how to determine viscosity experimentally. It comes up almost every year.
Paper 2 in detail
Paper 2 (Advanced physics II) covers topics 7 to 13: Further mechanics, electric and magnetic fields, nuclear and particle physics, thermodynamics, space, nuclear radiation, gravitational fields, and oscillations. This is the more abstract and conceptually demanding of the two content papers.
Further mechanics and fields
Circular motion, simple harmonic motion (SHM), resonance and damping, gravitational fields (force, field strength, potential, satellites and orbits), electric fields (force, field strength, potential, parallel plates), capacitors (energy stored, charging and discharging, RC circuits), magnetic fields (force on a current-carrying wire, motion of charged particles, electromagnetic induction).
Nuclear, particle and thermal physics
Nuclear and particle physics (Rutherford scattering, alpha, beta and gamma radiation, half-life, mass-energy equivalence, the standard model, fission and fusion), thermodynamics (specific heat capacity, latent heat, ideal gas equation, kinetic theory), space (stars, the HR diagram, cosmology, the Doppler effect, Hubble's law, the Big Bang).
Exam tip for Paper 2 Fields content (gravitational, electric, capacitance, magnetic) is the single biggest source of dropped marks on Paper 2 because the equations look similar but apply in different contexts. Build a one-page comparison table comparing each field side by side: Force law, field strength, potential, potential energy, equipotentials. Revisit it weekly.
Paper 3 in detail
Paper 3 (General and practical principles in physics) is the biggest paper in the qualification: 2h 30m, 120 marks, 40% of the A-Level. It is synoptic, so any content from across the spec can come up, but it has a strong focus on practical techniques, planning experiments, evaluating data, and applying physics to unfamiliar contexts.
A significant chunk of Paper 3 marks come from the 16 core practicals. Expect detailed questions on apparatus, method choice, sources of error, percentage uncertainty, log graphs, and how you would modify a procedure for a different goal. Edexcel's Paper 3 has a higher weighting on practicals than AQA or OCR equivalents.
Exam tip for Paper 3 Paper 3 is long. Pace is everything. Spend the first two minutes scanning the paper and identify the questions with the highest mark counts. Aim to leave the last 15 minutes for the highest-mark extended response, where breadth across the spec is rewarded over depth in one area.
Core practicals
Edexcel specifies 16 core practicals across the two-year course. You will not perform them in the exam, but you will be tested on the methods, the variables, the safety, the sources of error, and the underlying physics. Around 20% of the marks across all three papers come from practical-related questions – more than the 15% on AQA and OCR.
These are the 16 core practicals you need to know:
Edexcel A-Level Physics core practicals
- Determine the acceleration of a freely falling object
- Determine the electrical resistivity of a material
- Determine the EMF and internal resistance of an electrical cell
- Use a falling ball method to determine the viscosity of a liquid
- Determine the Young modulus of a material
- Determine the speed of sound in air using a 2-beam oscilloscope, signal generator, speaker and microphone
- Investigate the effects of length, tension and mass per unit length on the frequency of a vibrating string or wire
- Determine the wavelength of light from a laser or other light source using a diffraction grating
- Investigate the relationship between the force exerted on an object and its change of momentum
- Use ICT to analyse collisions between small spheres, for example by analysing video
- Use an oscilloscope or data logger to display and analyse the potential difference (pd) across a capacitor as it charges and discharges through a resistor
- Calibrate a thermistor in a potential divider circuit as a thermostat
- Determine the specific latent heat of a phase change
- Investigate the absorption of gamma radiation by lead
- Determine the value of an unknown mass or weight using the resonance behaviour of a metre rule clamped as a cantilever
- Investigate the behaviour of a simple pendulum
Where students lose marks Practical questions almost always ask for percentage uncertainty. The rules are: For a single reading use half the smallest division; for repeated readings use half the range; combine uncertainties using the right rule for the operation (add fractional uncertainties for multiplication/division, multiply by the power for powers). These are predictable and worth 3–5 marks each.
The practical endorsement
Alongside your A-Level grade, you receive a Pass or Fail on the science practical endorsement. This is a separate assessment based on your teacher's judgement of your competence in lab work throughout the two-year course, against five Common Practical Assessment Criteria (CPAC). There is no exam.
A pass in the practical endorsement is required for some degree courses, especially engineering, physics, and medicine. Universities check it when they receive your results. If you fail, your A-Level grade is unaffected, but the endorsement is recorded as Not Classified.
Mathematical content
Ofqual requires at least 40% of the marks in A-Level physics to test mathematical skills at Level 2 (GCSE higher) or above. Edexcel papers often sit slightly above this, especially in extended response questions. The maths content includes algebraic rearrangement, trigonometry, logarithms (essential for radioactive decay and capacitor discharge), exponential functions, basic calculus concepts (rate of change graphically), uncertainty propagation, and graph analysis (gradients, intercepts, log-log plots).
Most students who score an A or A* in A-Level physics also take A-Level maths. It is not formally required, but the speed and confidence that maths A-Level builds make a real grade-level difference. If you are not taking maths, a grade 8 or 9 in GCSE maths is the unofficial minimum.
5 tips for Edexcel A-Level Physics revision
Edexcel A-Level Physics has a heavier practical weighting on Paper 3 than the other major boards, so practical skills can swing a grade more than most students realise.
1. Drill the data sheet equations daily
You are given a data sheet with most of the equations. Drill yourself on what each one means, what each variable is, and what units it has. The students who lose marks are not the ones who forget the equation – they are the ones who pick the wrong equation under time pressure.
2. Treat Paper 3 like a separate qualification
Paper 3 is 40% of the A-Level – almost as much as Papers 1 and 2 combined. Build a specific revision block for it in the run-up to exams, focused on the 16 core practicals, evaluation questions, and synoptic answers. Past Paper 3 questions are the single best preparation.
3. Practise multi-step calculations under time pressure
A-Level physics calculations are rarely one-step. A typical 5-mark question involves three or four sub-calculations that must be done in the right order with the right units. Past paper calculations under timed conditions are the single best preparation.
4. Drill the core practicals like exam questions
Do not just memorise each method. Learn the variables, the controls, the percentage uncertainty calculation, and the graph you would plot. Past paper questions on practicals are some of the most predictable mark-grabbers in the whole course.
5. Use past papers as a diagnostic
Doing a past paper and putting it back on the shelf is wasted work. Mark it honestly, write down every topic where you lost marks, and revise that specific content before doing another paper. The biggest jumps in physics scores come from fixing recurring weaknesses, not from doing more papers.
