    Anyone else doing this, and has got ANY idea of what we should revise?

    There's nothing in the specification


    You mean PSA6?

    It's synoptic, so they could ask you about anything, theoretically. Try and get your hands on some past papers, and make sure you're fairly comfortable with most of the course, particularly how to apply the equations.

    im trying to do some past papers now and am finding it so difficult to link between different equations but i have written down a few of the link the exam board have used which might help with revision:

    1. F=mg and F=GMm/r^2
    therefore g=GM/r^2

    2. f=v/wavelength and E=hf
    therefore E=hv/wavelength
    and if question is about light then v=c therefore E=hc/wavelength

    3. p=E/t and E=F*d
    therefore p=F*d/(t)
    therefore p=Fv

    4. v=wr (w=omega) and w=2(pi)/T
    therefore v/r=2(pi)/T

    5. F=mv^2/r and F=GMm/r^2
    therefore mv^2=GMm/r

    has anyone else got any more???
