Learn the whole KS4 / GCSE Physics course
Structured around the main KS4 Physics topics: Forces, Energy, Electricity, Magnetism and Electromagnetism, Waves, Particle Model, Radioactivity and Space.
Concise topic notes and key equations written for 14–16 year olds.
Handy summaries of common relationships, symbols and units.

Practise with questions and daily challenges
Topic-based quizzes with instant marking.
A Daily Challenge mode to keep you practising little and often.
XP and streaks to help you see your progress over time.
Questions are designed to feel like real GCSE items without copying any past papers.

Smart Physics “Coach” tools - Interactive calculators that don’t just give an answer – they help you set the problem up correctly.

SUVAT Coach – constant acceleration questions with s,u,v,a,t.
Waves Coach – connect wave speed, frequency, wavelength and period.
Terminal Velocity – explore drag vs weight and maximum falling speed.
Ohm’s Law Coach – link potential difference, current and resistance.
Density Coach – relate mass, volume and density.

Each tool:
Guides you to choose the unknown quantity.
Checks your inputs for sensible values.
Shows the result with correct units.

Study, revise, then check understanding.
Use the tabs along the bottom to stay organised:
Home – KS4 Physics hub with quick tools and topic shortcuts.
Study – browse topic notes and explanations.
Practice – tackle question sets by topic.
Challenge – daily mixed practice with XP rewards.
Tools – jump straight into the Physics coaches.

Now with a Glossary of Key Terms.

You can start from any angle: read the notes, try a quiz, or go straight into a tool when you’re stuck on a calculation.

Designed for students and teachers.

KS4 Physics works well for:
Students revising independently at home.
