AQA Physics Unit 1 Re-sit!!!?

Hello,
I have my phsics unit 1 resit on the 9th of june, two days from, the first time i took it it was horrible and i got a C, so i need some help on the subject, i pretty good with Moments, optics and that other stuff but not so much with SUVAT and vectors which is why i failed last time!
HELP ME!
Thanks
WOW no answers, are all people on yahoo answers morons! Hasnt anyone done further education from compulsory school?

Hey! Who’s the moron that failed in the first place :P

For SUVAT, i find it easiest to write down all the values they give you, eg. S,V,A, and then what they’re asking you to find, eg. U. All you then have to do is find the equation with these letters in, in this case v^2 = u^2 + 2as, stick your numbers in, rearrange, and there you have your answer!

Vectors is a bit trickier, just remember to draw your triangle or whatever, and know your trig equations (only soh cah toa, they’re not going to make you use sine/cosine rule). I found working through the summary questions (if you have a textbook) or doing past exam questions (although there’s only one or two online) quite helpful.

This probably won’t be of much help, but meh :P , good luck tomorrow!
