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

Haha I think it's the best example to simplify a question

haha, thanks

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.

Hmmmm curious as to what questions he gives then

A good diagram gets you around most qs

Only example i could find atm, probably easy to smart people but unfortunately im not blessed with much of a brain

16. 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 I shorten like crazy

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

No, I mean finish the syllabus hahaha

Ahh, so I guess it's just past papers from now then!

Yes! Used to watch everyday but watch a little less now. Love him (and he lives in the same borough as me ahh!)
