    honestly if aqa are following their 6 marker trend this year i think it'll be on describing and explaining someones results or planning your own experiment just a thought really
    True, but I do think there may be a question on describing the differences between Fission and Fusion, however I may be wrong :s

    Don't think it will be a six marker :/

    Any topics that people just really don't understand? I'm willing to help
    Hi, could you help me understand the effect temperature has on current.

    Revising more of how to carry out experiments, variables. Describing and explaining...

    Like he/she said, Revise all the bulky subjects. (you'll need to properly know this stuff) But all the equations and stuff is common sense.

    P2: Radiation, Fission, The formation and life cycle of stars, Terminal Velocity, and a bit about stopping distances. All the equations and stuff are on the sheet, and just apply the knowledge you already know to that question. The rest is quite easy.

    P3: X-Rays, CT Scans, Ultrasound,(overall just the whole medical bit) and Lenses and Refraction.
    Then the stuff about motors, circular motion etc is kinda easy and takes a small bit of revision.

    I'd recommend going over the bulky subjects, because I reckon P3 Will contain A LOT of it.

    Hey would anyone be able to explain the 3 core cable/ plug to me? I'm confused as to how the neutral wire is at 0v but has a flow of current through it! And also if possible how a fuse and earth wire work together to prevent overloads.. Thank you!

    Hi, could you help me understand the effect temperature has on current.
    With a filament bulb, high temperatures cause the ions in the filament to vibrate, hence making it harder for electrons to flow through the bulb so there will be a higher resistance.
    This means that the bulb is a non-ohmic conductor, since the resistance is not always the same.

    For a given voltage, if the resistance is increased, the current in the circuit is decreased. This can be shown on a pd-current graph as a curve that begins steeply (low resistance) and then bends to become less steep (high resistance).

    Yeah those titrations questions and the biology one about the diffusion in the egg completely messed me up

    could you help me with terminal velocity/drag force?
    These are the 5 key stages about terminal velocity of a parachutist.
    1. Accelerates rapidly because falling force is much larger than air resistance.
    2. Accelerating (slower) because air resistance has increased slightly.
    3. Constant speed because air resistance is equal to falling force. Terminal Velocity has been reached.
    4. *opens parachute* Parachutist slows down.
    5. (slower) Constant speed because air resistance is equal to falling force. Terminal velocity has been reached.

    Terminal velocity = when forwards force is equal to air resistance (usually top speed).
    Larger surface area = slower terminal velocity.
    As velocity increases, air resistance increases at FASTER rate, i.e NOT directly proportional.

    Hope this helps!
