40 everyday devices, 400 GCSE Physics questions. From air fryers to electric scooters, every page takes a device you use and asks 10 exam-style questions about the physics inside it – calculations and explain questions, from Foundation to Higher, each with a full worked solution.
Course: Combined Science + Separate Physics | Tier: Foundation + Higher | Labels: F, F/H, H; anything Separate Physics only or Higher tier only is marked S only or HT
✏️ Paper first: work out each answer on paper, then open the solution to check. Use FIFA for every calculation: Formula, Insert, Fix, Answer with a unit.
📖 New article: how a vacuum flask keeps drinks hot – a labelled diagram, a clear explanation of conduction, convection and radiation, and 10 questions with answers.
