What equations do I need to know for the Edexcel IGCSE physics exam for the Energy Resources and Energy Transfers topic?

In the list below the equations are grouped into the ones that need learning for IGCSE Edexcel double award (4SD0) and Physics only specification (8463). The bold type equations are Paper 2 only.

Some of the equations do not need to be learnt but will be given on an insert in the paper. These equations are at the end of the list. The equation list required for OCR, CIE, AQA trilogy and combined science are almost if not identical. One notable exception is the AQA specification requires memorization of the Elastic Potential Energy equation.
