What is the best definition for static electricity in GCSE Physics?
A net positive or negative charge on an object which is insulated from from the ground or earth. The key thing is the charge cannot flow, hence static or stationary. We usually demonstrate static charge by rubbing insulators like polythene and/or acetate with a dry cloth but obviously conductors can become charged with static or stationary charge, otherwise the metal dome of the Van de Graaf generator could not be charged, the metal plates in a capacitor could not become charge, etc, and the more everyday instance, cars (usually steel) could not gain enough charge to give us that little shock when we kindly provide a connection to earth. I think this is a more complete answer BUT look at the mark scheme for any past paper from the exam board you are studying and, if it is easier to understand or remember, learn that! To pass an exam you just have to please the examiner, not necessarily have the most accurate answer. Look at the website of the board you are studying, some boards put mar
