    Based on the ecf rule, you'll get the first bit wrong but not the 2nd time.
    Ok hopefully! I got 7.2 anyway on the last one so that's not a problem.

    On the P2 paper I think I got the top speed thing wrong (I got 17m/s) and I got the kinetic energy one wrong, I've probably made a few mistakes with the whole how science works stuff ad also the last comparison question. On P3 there's nothing in particular that I think I've definitely got wrong but just a few uncertainties like with the power range thing I got 0.125 which I don't think is right and also the pendulum experiment improvement question was a bit sloppy as well as the bus question. I find P1 super easy so I'm hoping for a high A* in that, also got 48 on the thermistor ISA paper so I hope that those will bring up any mistakes. What do you think you got right/wrong?

    All of the answers you have put there are exactly what I put! I don't think I got full marks in p3 6 mark (even though I used all the space) I spent ages on that pendulum question for what conclusions could be made from the data an eventually ended up with answers that I think are right. I was unsure on loads of questions but tbh my memory is so bad that I cant remember half of them!

    Yeah I used all the space on the 6 marker and more but feel like I missed things out😅 for the pendulum one I think I put 'the longer the pendulum, the longer the periodic time' and 'the mass of the pendulum does not affect the periodic time' but I'm not sure if you had to directly talk about the oscillations thing :/

    Overall how would you rank all the exams (B3,B2,C2,C3,P2,P3) from the easiest and ones you did best in , to the hardest and the ones you did worst in. For me it's: easiest: B2
    C2
    C3
    B3
    P2
    Hardest: P3

    yeah that's what I got. Which way did you put the arrow for the motor effect question?

    Makes me feel better that someone else put it too, I hate analysing data because it's always awkward to phrase it in a way that they would in the mark scheme

    to be honest it seems like it was graph B , the velocity leveled off which was good because it reached terminal velocity. there was no graph which had faced towards the x-axis. probably before it hit the ground. just my choice.
    didn't the question, say there was no air resistance?

    Q1 ) Electricity (resistance) - investigation
    Q2) Plum pudding (atom structure)
    Q3) Nuclear reactions (Nuclear fission and fusion)
    Q4) Car safety and seatbelts (Speeding issues and car safety) and momentum
    Q5) More on Electricity (coulombs )
    Q6) Forces and Motion ( the rocket)

    Q1
    a) line is constant
    b) C because greater resitance due to greater current
    c) --
    d) voltmeter in parallel
    e)resistor (look on google)

    Q2
    a) what is the sphere part of the pudding model?

    the sphere is positive

    b) why was the old particle model replaced?

    the nucleus took most of the space of an atom whille the electrons repel the alpha particles

    bi) why is Michael faraday sure his investigation is valid?

    more than 100000 experiments were done meaning the data is very accurate and
    answers their hypothesis.
    c) 6 marker - nucleus of an atom

    Q3
    a) what is nuclear fission?

    when a neutron is fired at a nuclei to form 2 daughter nuclei

    b) cant remember
    c) cant remember
    d) no idea.
    e) What is the natural resource of nuclear fission?

    space.

    ei) give 2 advantages of nuclear fusion than fission
    - more energy
    -non-radioactive

    eii) give one main consequence of nuclear fission.

    Q4

    a) what is braking distance

    the distance the car takes to stop , after the brake is applied

    b) give one factor affecting braking distance
    - enviroment
    -poorly maintained vehicle

    c) cant remember

    d) cant remember

    e) why is safer to use seat belts than no wearing seat belts in a collision? (4 marks)

    f) momentum

    answer = 5m/s

    Q5)

    a) 0.7A

    b) calculate the charge in 30 seconds or sumthin

    c) calculate the energy transfered

    d) why does the heating element heat up?

    positive ions resist the passage of electrons moving causing kinetic energy to cause more vibrations making more heat

    Q6)

    Velocity decreases
    because the object reaches terminal velocity , due to the air resistance and gravity.

    what is the difference between velocity and speed?

    velocity is speed in a given direction

    b) calculate the kinetic energy

    0.5mv^2

    m = 0.05
    v = 12

    answer = 3.6J

    bi)gravitaional potential energy = i got 3.6J

    bii)calculate the Ep

    7.2J

    c) graph B

    d) 30 degrees and 45 degrees are related since they have similar shape and similar heights and range
    I said that an advantage of fusion was that the materials used were widely available as they come from seawater, do you think that would get the mark?

    correct!

    you still get the mark
    i done this quite quickly , but most might not be right.
