    x = Asin(nt + \delta) makes it pretty easy.

    (all SHM can be described using that equation, or the same using cos)
    There are a few more equations in our M3 textbook that must be learnt also

    Plus our teacher used omega instead of n, which got confusing once we used angular displacement rather than normal displacement

    All you need to remember is

    wax if you cba deriving in head

    v² = w²(a²_0 - x²)

    And the rest you can just get from the general equation

    True (although isnt it a2 - x2 )

    At least the SHM in the physics course is very basic compared to M3, should help a lot

    It is yeah lol

    Was testing you

    Also it'd make sense because when x is amplitude, velocity is 0,so it falls into place

    Starting to think I made a big mistake taking M3, especially because I have to resit M2 and I can't even get my head around that anymore

    You'll be fine!

    All you ever need, is a diagram with everything labelled

    Every question has a way of going it

    Eg rigid bodies/statics (Rachel knows I always use this as an example lol)

    Resolve vertically
    Resolve horizontally
    Take moments about a point which will eliminate most variables (normally where there is reaction and friction)

    And then solve simultaneously to get each part you want

    Has everybody got their statement of entry slip yet?

    I'm still waiting for mine yet last year I received mine late march.
    Also, when is everybody's first and last exam?

    I was given mine in Jan/Feb I think.

    That's what I always do, I think I'm just crap at figuring out what to do after that

    Ooooh you're doing M3, sorry, that was probably a bit patronising then

    Really helps with Physics tho.

    If you need any help with mechanics I can try and help btw.

    That's all there is to it? After that, it's just standard simultaneous equations

    So just sub one into the other

    I don't remember many questions in our examples that were that straight forward, but then again our teacher writes his own problems for our examples which are always quite a bit more complicated than needed.

    A good diagram gets you around most qs

    Probably weirdest q ever posted on this thread but...
    When you were younger, as in Year 6-9, did your school sign you up to pages like SuperclubsPlus or GoldStarCafe? It had a similar layout to TSR, only that it was a lot more censored (obviously, as it was for children). I used to use it a lot :P

    That is harder than standard level

    Also, I love how people spend half the page writing the question :mmm: I shorten like crazy

    I think I use less than half the amount everyone else does
