    Coming out of the exam room I was feeling pretty happy but now I'm not so sure did you start your axis from (0,0)?

    I think I'm happy with my values calculated, for g especially its the uncertainties I'm not sure about.
    Yes I did start from (0,0) did you ?

    yes I did, phew! It thought the scales fit exactly, but I met a lot of people who didn't which made me nervous!

    No I was really surprised at how nice the scales were too, glad it wasn't just me (:
    You ready for the experimental one ?

    hopefully, I find that they are either really horrible or really nice so hopefully it's the latter! But I do feel it'll be ok! How about you?

    Also, what did you put down as the units for the gradient and root m? I got a bit paranoid about that too!

    Ugh I messed up the last 2 questions. I think I calculated k incorrectly but hopefully I should get ecfs!

    To anyone who broke the axis, did you find that one of your error bars didnt fit on the graph paper? (because mine did but everyone else's didnt seem to - but then i may have used different scales!)

    Thanks! Well at first I was really upset because I'd done so well only to royally f*ck up the last 10 marks, but then I found out its worth 5%, so essentially 5 marks = 1%. So Ive got at least 1-2% Yaay!!

    So long as I do well in Tuesday's PH6,PH4 & PH5 I should be okay. Though it was kinda cheeky of the examiner, he usually has the questions in smaller chunks and there was no analysis of the data ie a comment on your graph question

    For root m I didn't know so just put kg, not sure what I put for the gradient if I gave it a unit at all oops :/

    I'm not prepared for that at all!! We did a prac today for it, and that was our first!!
    I asked my teacher for data on the previous past papers so that I could practise the questions ( as we wont get to do another prac now) but he just said he can't help me :/ So Im dreading Tuesday !

    For table sqrt(m) values did everyone remember to multiply by only 2.5% to get absolute uncertainty values (because m^(1/2) means half the percentage uncertainty)?
    Most people I know didn't...

    In my school we have only done one Experimental task for Tuesdays exam, and we did it yesterday.
    I want to practise the questions so I know what to do, does anyone have some data for the other past papers that I could use to complete the papers please ?
