Ee = 1/2 k e2
e is the EXTENSION, not the length, and it is squared: two separate marks to lose.
Current GCSE 8463 policy: The full AQA GCSE Physics 8463 equation sheet is provided with both papers in 2026; use fluency practice to learn selection and rearrangement, not to memorise the list.
| Symbol | Quantity | Unit |
|---|---|---|
| Ee | elastic potential energy | J |
| k | spring constant | N/m |
| e | extension | m |
Work each one out on paper first, then reveal the mark scheme and tick the marks you actually earned. That is exactly how you should mark past papers.

Exam tip: Work out the extension in metres as a separate first line. The equation only holds while the limit of proportionality is not exceeded, so look for that phrase in the question.
