    How much do you think doing most of the past papers will help if I have the average knowledge on most of the topics?

    You're clearly working for OCR and will rat all the people who are going to PM you now.

    Hmmm from some gentle stalking I think we have a quite a bit in common: programming, computers, chemistry, maths, further maths, gym
    You hoping to do CompSci or something at Uni?

    Dammit, yeah I did mean Galileo.
    All fixed now.

    It's tomorrrooowwwwww, gleep! I'm feeling a lot more confident this time round though. We had a new lady start recently at college who's head of maths and science and she's been amazing. She actually spent a good three hours of her time helping me with the concepts I was struggling with, giving extra questions, marking them and giving me pointers for giving better answers in some cases. She's been amazing, I can't thank her enough. I'm going to do some last minute past papers today and some questions on the bits I'm still a bit unsure on, but for the most part, feeling much more confident.

    I'm hoping for a more maths-y paper this time round, too. I didn't think January's paper was too bad but I do prefer the maths side of it.

    What does everyone think is very likely to come up this time round??

    I think vectors look promising

    Anyone got a model answer for how a crumple zone works?

    Personally I think stress/strain and all that material stuff with feature. There was only that YM question in January if I'm remembering this correctly. SUVAT will most likely come up and tension will too probably (as much as I hope it doesn't).

    Very helpful notes, however it's important to state that Galileo used a smooth inclined plane for his experiments so that they could be slowed down in order to time the motion

    thanks for this, I better go learn how to tackle the 7 marker.

    Can anyone explain whether its stronger to have springs in parallel or series and what difference does it make?

    there isn't anything on it in the book :/

    My notes on Crumpl Zones

    -Parts of the car (Normally Front and Back) are designed to collapse during collision.
    -So in an accident this will increase the distance of the force.
    -Time is also increased which will decrease the deacceleration.
    -Decreasing the deacceleration will lead to a smaller force because of F=ma.

    I think it's stronger to have them in series. I think it's because the force is then shared out between them and it's going to stretch less, whereas if you are putting the same force on two springs in parallel, they're just going to stretch even further.

    Where does it say about series and parrallel in the spec? Can't find anything about it

    This answer is more appropriate for seatbelts and airbags i think - crumple zones are designe to absorb some of the energy from a collision

    Its not in the spec and that's why I haven't learned them but I've just seen a question on one of the legacy papers on it and that made me ask..
