A blog covering and explaining the Edexcel IGCSE Physics specification for the 2016 summer exams. If you are doing just double science, you do not need to learn the stuff for paper two, if you are doing triple you will need to learn all (GOOD LUCK!) I have separated the papers to make files easier to find. Hope it helps :)
Energy can never be 'lost' or 'used up', only every transferred. For example, when you turn a light on, electrical energy transfers to light energy (and a little heat energy).
