    if that was asked in the exam probaly around half of all students o wouldve answered wrong.
    Absolutely agree with you! There is always one definition question. Last year it was half life.

    Motor effect!!!! ANYBODY!!!!!!!!
    The current running through the coil around the iron core produces an alternating magnetic field. This interacts with the permanent magnetic field, and produces a resultant force.

    Would i be correct in saying the following:

    Through an increase in impact time, there will be a decrease in impact force, due to the momentum and kinetic energy having to travel over a further distance, thus getting lost in the process. We can also see through the equation wd/d=f=impact force (wd=work done), through the increase in distance, the impact force will decrease. Alongside this, through the equation f=ma, and a=(v-u)/t, we can see that an increase of (impact) time, this will decrease the (de)acceleration, and in turn decrease the impact force. Therefore, an increase in impact time will result in a decrease in impact force.

    Would this be correct?

    I only do P2 I'm afraid, sorry I should have said!

    • But the resistance decreases as the temperature increases.

    • Hot conditions = Reistance falls / lowest

    • Cold Conditions= Resistance goes up / highest

    • Thermistors are used in Thermostats and Temperture Detectors in car engines!

    This is the information in P2,I have no idea if it is relevant to P3.

    Hope it helps!

    No because you are too right and your answer radiates A-level giberish . P.s just joking thats a very good answer , that would definitley get u 6 marks.

    New rumours are spreading that AQA P3 paper will be very easy , because in previous years there have been harder papers.Maybe even nice than the C2 and C3 papers .
    I swear to god that better be the case :banghead::banghead::banghead:

    p3 i think 6 marker will be X-ray(and/or CT scan)/Ultrasound comparison or +/- OR center of mass
    That would be awesome it's basically a comprehension

    Does that mean that P2 is going to be like the biology paper? Impossible 😂

    Motor effect!!!! ANYBODY!!!!!!!!
    The motor effect is when a wire carrying a current is placed in a magnetic field and experiences a force as a result. As the current flows through the opposite sides of the coil in opposite directions, opposite forces act on each side of the coil- 1 up and 1 down which leads to the coil rotating.
