    1700m (2.s.f) distance travelled by plane, anyone ?
    if there was force going forward so F-R=ma then 1700 m is correct.
    but if the only force acting was the resistive force then 851m is the right answer.
    I wasn't sure if there were any forces acting forward since the question said the air was travelling the same as in part ii

    Momentum - it's new to the AS spec, so I think it's likely to feature in the exam.

    But it asked for deceleration, not acceleration.
    They might give you it. They do in M1, and M2 for maths. Its only 1 mark, they said deceleration. But the negative could imply negative acceleration.

    Find someone that teaches physics at your school and find it.

    such a **** test, didn't finish, waffled on most questions got all the calculations right though but i think i flopped. around 30, can i still get an A if i get 70 in paper 2 or are they independent tests?

    Based on the topics in the first test where do you think the bulk of the marks will be in tomorrow's test?

    Topics that weren't covered on paper 1 and could be on paper 2...
    Quarks & leptons, particle zoo, mesons, Feynman diagrams, Strangeness
    Charge, voltage, component characteristics
    Moments, stability, free fall, motion graphs, SUVAT, vehicle safety, work, energy, power, efffciency
    All of optics

    Particle stuff bound to come up as there was usually another question for particles in the previous papers (before new spec)

    Does anyone have model answers for the specimen papers? Preferably could someone tell me how to work out question 1.1 on specimen paper 2

    You are given that it is 3.5*10^3 lines per meter but for ease consider it 3.5 you know the lowest decimal place value you can measure to is 0.1 therefore the uncertainty if it were a reading would be 0.05 but considering that it is a measurement there is 0.5 at either side therefore the uncertainty is +/-0.1

    To calculate as a percentage divide 0.1/3.5 (or (0.1*10^3)/(3.5*10^3)) and multiply be 100 to get 2.9%

    This is wrong, aqa have specifically said, the uncertainty is always +-1 of the lowest signifamt figure. Why because we don't no anything about experimental method, therefore taking it as 1 is to be certain. Always take +-1 of lowest sf if not specified method. Example 5.64 mm will be 0.01 mm or 5.3 will be 0.1mm

    I had to guess a couple earlier on but overall was pretty rushed throughout
