GCSE Physics - Static Electricity | Build-up of Charge on Insulating Materials (2026/27 exams)

⭐️ Check out our website https://www.cognito.org/ ⭐️ ** WHAT'S COVERED ** 1. What is static electricity? The build-up of charge on insulating materials. Why most materials are electrically neutral. 2. How static electricity is created by friction. The transfer of negative electrons between materials when they are rubbed together. The difference in behaviour between conducting and insulating materials. 3. How insulating materials become charged. An explanation of how a polythene rod and a cloth become charged. An example showing how an acetate rod and a cloth become charged. The key principle that only negative electrons are transferred. 4. How static charge causes sparks. The build-up of a potential difference between a charged object and an earthed object. How electrons jumping across a gap creates a spark. A real-world example of getting a static shock from a car. ** EXAM BOARD SPECIFIC INFO ** AQA - Only triple science (both foundation and higher tier) IGCSE Edexcel - Only triple science (and only higher tier) Edexcel - Only triple science (both foundation and higher tier) OCR 21st Century - Only triple science (both foundation and higher tier) OCR Gateway - Only triple science (both foundation and higher tier) ** CHAPTERS ** 0:00 What is Static Electricity? 0:35 How Friction Causes Static Electricity 1:03 Static Charge in Insulating Materials 1:32 Charging Different Materials (Polythene vs Acetate) 2:08 How Static Shocks and Sparks Are Created 2:47 Static Charge Build-Up on Conductors ** PLAYLISTS **    • KS3 Biology      • KS3 Chemistry      • KS3 Physics      • GCSE Maths (9-1)      • GCSE Biology (9-1)      • GCSE Chemistry (9-1)      • GCSE Physics (9-1)      • A-Level Biology   #GCSE #Physics #study #revision #school #exam #AQA #OCR #Edexcel
