Hi this is my first post on TSR so sorry if its not that great. Anyway im studying A2 Edexcel physics, i got a D at AS (but im retaking the mechanics exam so hopefully itl go up), and i dont study a level maths. So basically my question is, are all of the equations on the exam sheet where given the only ones we will need or are there more i need to memorise? I frequently find myself not knowing what equation to use on homework and in the lessons and i just wanna do everything i can to make sure i get my target grade, and i dunno if theres things im not memorising that i should be ?
