    Seems legit, looks like they have some notes for each part of the spec.. thanks!
    and haha I'm they won't mind!



    I have a whole week until unit 4 so figured I don't want to leave it as last minute as I did today for unit 5!
    And ah my school doesn't do unit 4 for us during January, what are you aiming for?
    I'm aiming for an A but I only need a B to get into uni. How did you find unit 5?

    I'm aiming for a B because that's all I need haha! And it was better than I thought it would go to be honest, I hadn't really prepared myself for it so I was expected a fail but a few of my friends taught me pretty much the whole of medical physics and the universe before the exam, so I got pretty lucky when that MRI question came up! But I know there's a chance I've only gotten a C so my plan is to smash Unit 4!

    I found unit 5 alright. I revised MRI, nuclear reactor and the universe and it all came up so I was happy. Definitely made some mistakes on the calculations but I'm hoping for an A

    I got a C on unit 4 too, and I haven't looked at it since January haha, I really need to start!

    There were no circular motion questions in the previous paper so I think that will definitely come up.

    Working out specific heat capacity

    Brownian motion experiment

    a experiment about period and angle of oscillation of a pendulum came up in June 11 paper 5 marks

    G - just selecting and using that equation. You won't need to derive it, although it's from plugging g-F/m into F=GMm/r². Use it when You know the mass of the larger object, the distance between the two.
    H - When an object is falling to the Earth's surface, it will fall with an acceleration of a = F/m, and since F due to gravity = gm, substitute that in for F and a = gm/m, cancel the m's and you're left with g.
    I - you just need to realise that the force due to gravity = centripetal force, therefore GMm/r² = mv²/r. You can combine these equations a million different ways, and you sometimes need to realise that v = 2π/T and substitute it in sometimes. This is also the equation you derive Kepler's Third Law from. (T²/r³ = 4π²/GM)

    On a side note, I'm bricking it for this exam after G485 :/ got a C in January and need an A overall.

    Can they ask us to explain why T is independent of displacement in SHM?

    I think i am, i just need to make sure i gain marks from the written questions. Calculations are not usually a problem.

    When i did the paper in jan, i got all the calculations correct apart from one but i lost many marks from the written questions.

    I got 72/90 in jan but i'm aiming for A* this time round.

    Wow those look really good and similar to the medical imaging ones from G485 you didn't happen to do those by any chance did you?
