Free A-Level Physics Solver

A-Level Physics (AS + A2) is a two-year course taken in Year 12 and Year 13, culminating in three linear papers of 2 hours each. AQA, Edexcel (Pearson), and OCR cover broadly the same DfE core content, with minor differences in optional topics and exam structure. A-Level Physics sits alongside A-Level Maths and A-Level Chemistry as the archetypal 'Russell Group science' combination, required or strongly preferred for Engineering, Physics, Computer Science, and Medicine at most top UK universities.

The AS-level content (Year 12): measurements and errors, particles and radiation, waves (standing, progressive, polarisation, diffraction), mechanics (kinematics, forces, momentum, energy), materials (Young's modulus, stress-strain), and electricity (current, resistance, circuits, EMF). A2 (Year 13) adds: further mechanics (circular motion, oscillations, SHM), thermal physics (specific heats, ideal gas, kinetic theory), gravitational and electric fields, magnetic fields and electromagnetic induction, nuclear physics (radioactive decay, binding energy, fission, fusion), and an optional topic (astrophysics, medical physics, engineering physics, or turning points depending on your specification).

Exam marking is explicitly method-aware. A 5-mark calculation question typically splits: 1 mark for stating the relevant equation, 1 mark for correct rearrangement (if needed), 1 mark for correct substitution with units, 1 mark for correct numerical calculation, 1 mark for final answer to appropriate significant figures with unit. The solver above follows this exact structure so your working matches the mark-scheme break-down.

A-Level Physics has a reputation for being hard, and the hardest skills to build are: (1) writing long-answer 6-mark 'explain' questions — these require structured prose, not just equations, and reward students who follow a clear logical thread; (2) handling multi-step calculation questions where you have to chain three or four equations; (3) drawing and interpreting graphs, especially on practical assessments; (4) understanding when to use energy methods vs. force methods vs. momentum methods — they all work but the right one saves time.

The solver treats your input as an A-Level Physics question. For calculations it labels the equation used, shows substitution with units, cross-checks with an alternative method where possible, and reports the final answer to the significant figures the board typically expects. For 'explain' questions it structures the answer as Point-Evidence-Link paragraphs.
