A collection of Edexcel International AS and A-Level equations, grouped by topic. Use it alongside the official specification and the formulae supplied for your exam. Practise identifying the right relationship, understanding its conditions and using it in unfamiliar questions.
Check the units before substituting: practise physics unit conversions, or work out what a graph gradient means.
This resource targets Pearson Edexcel IAL, with AS and A2 groups identified below. It is not a Cambridge International A-Level or UK A-Level formula booklet. The official specification contains the course requirements and formula list; use the booklet supplied for your own paper when practising timed work.
Pearson Edexcel International AS/A Level Physics — specificationOriginal academy revision aid. The exam boards do not endorse this sheet. A supplied equation does not choose the right model for you: identify the quantity, check the conditions, convert units, rearrange and then substitute.

An equation belongs to a physical model. For example, the familiar constant-acceleration equations require constant acceleration, and Ohm's law describes an ohmic conductor under constant physical conditions. A correct substitution can still give an inappropriate answer if the chosen model does not fit the situation.
Before calculating, identify the system, quantities, assumptions and direction convention. If acceleration varies, reading a graph or using a different model may be necessary. The formula sheet is a reference; the topic notes explain the conditions that make a relationship useful.
No. It is an independent revision reference. Use Pearson's current specification and the materials specified for your exact exam to confirm what is provided. International AS and A-Level Physics are distinct from UK domestic A-Level Physics, so check your qualification code before comparing resources.
