Physics equations
GCSE & A-level
AQA
Every equation by topic, with what each symbol means and its unit. Switch between GCSE and A-level. The data sheet gives you some in the exam — but recognising and rearranging them fast is the real skill. Flip on Test yourself to drill recall.
Your board provides some of these in the exam and expects the rest from memory — the goal is to know them all.
Energy
| Kinetic energyEₖ (J), m (kg), v (m/s) | Eₖ = ½ m v² |
| Gravitational PEg = field strength (N/kg), h (m) | Eₚ = m g h |
| Elastic PEk (N/m), e = extension (m) | Eₑ = ½ k e² |
| Specific heatc (J/kg°C), Δθ (°C) | ΔE = m c Δθ |
| PowerP (W), E (J), t (s) | P = E / t |
Electricity
| Charge flowQ (C), I (A), t (s) | Q = I t |
| Ohm's lawV (V), R (Ω) | V = I R |
| PowerP (W) | P = V I = I² R |
| EnergyE (J) | E = P t = Q V |
Forces, motion & waves
| WeightW (N), g (N/kg) | W = m g |
| Work doneF (N), s (m) | W = F s |
| Accelerationa (m/s²) | a = Δv / t |
| Newton's 2nd lawresultant force (N) | F = m a |
| Momentump (kg·m/s) | p = m v |
| Uniform accelerationu, v (m/s), s (m) | v² = u² + 2 a s |
| Wave speedf (Hz), λ (m) | v = f λ |
