# SolvedPhysics

> Free step-by-step physics equation solvers for UK GCSE (AQA, Edexcel, OCR) and A-level students. Each solver chooses the right equation, rearranges it, converts units to SI, and shows every line of working the way examiners expect. Written and checked by Mehmood Kakar, a physics teacher and engineer with 8 years of teaching experience.

## Solvers

- [Kinetic energy calculator](https://solvedphysics.com/gcse/energy/kinetic-energy-calculator/): Find kinetic energy, mass or speed with Ek = ½mv². Converts g, tonnes, km/h, cm/s, kJ and MJ. Includes common mistakes, worked practice questions and FAQs.

## About

- [About SolvedPhysics and the author](https://solvedphysics.com/about/): Who writes and checks the content, and how it is checked against the AQA GCSE Physics (8463) specification.

## Key facts

- For AQA GCSE Physics (8463), all physics equations are printed on the exam equation sheet; marks are mainly lost on choosing, rearranging, unit conversion and showing working.
- SI units used throughout: energy in joules (J), mass in kilograms (kg), speed in metres per second (m/s).
