GCSE Physics guides

Practical help with the parts of physics calculations that lose the most marks. Each guide links to the solvers so you can practise straight away.

How to rearrange physics equations

The balance method, formula triangles and five worked examples, including square roots.

Every SI unit, prefixes from nano to giga, and the conversions that cost marks.

A four-line layout for every calculation, plus rounding rules and multi-step questions.

Seven worked questions, from 2-mark substitutions to a falling ball that links GPE and kinetic energy.

Six worked questions on Ep = mgh, including height, mass, the Moon and a crane power problem.

From dividing by only one term to missing the square root, with right and wrong examples.
