ive been doing past papers, and there seems to be loads on forces, and barely anything on stuff like nuclear fusion? and static electricity comes up all the time. im not as worried about p2 as p3 though!
aaaah yeah thankyou! maybe there will be stuff on nuclear fisson/fusion then or life cycle or stars maybe as it hasn't appeared much before?! yeah i know what you mean and stuff on a.c and d.c. current has appeared a few times and i have a feeling something to do with them potential difference-current graphs may come up and like explain about resistance of a filament bulb in terms of electrons and ions?! thanks for your help:) and yeah luckidly im not doing P3 this time:'D! good luck:') <3
hey, there seems to ALWAYS be a question in every single past paper which asks why something is useful for preventing injuries on a driver or whatever. For example 'why do airbags prevent injuries?' and the answer for 3 marks is always:
To increase the time taken for the (driver/child) to stop (1)
To decrease the rate of change in momentum (1)
Reduces the force on the (driver/child) (1)
If you say all of those points it will be 3/3 marks. Seriously a question like that always comes up. Good luck everyone :D
