    oh there are more!

    moment= force *perpendicular distance between line of action and pivot

    kinetic energy = 1/2*mass*speed2

    Basic but important Physics formulae...

    Need to know:
    V=IxR
    I=V/R
    R=V/I
    Q=Ixt
    -----
    P=VxI and P=I²xR
    E=QxV and V=E/Q
    E=Pxt and E=IxVxt (These two are to calculate Energy, but can be used to find time)
    -------
    F=m x a
    W=m x g.f.s (gravitational field strength, they accept g in place of g.f.s though)
    D=m/V
    M=F x r (To calculate Moments, Force times Perpendicular Distance)
    s=d/t
    a=v1-v2/t or a=F/m (first formula is change in velocity over time)
    f=1/T (T being time period)
    v=f x (wave formula)
    Wd=F x d
    PE=m x g.f.s x h
    KE=1/2m x v²
    -------------
    Need to know two others:
    Efficiency= Useful work output / Total energy output
    Transformer Equation: Primary Coil Voltage = No. of turns on Priamry Coil
    Secondary Voltage No. of turns on Secondary

    If you want to know what any symbol is just ask me, (i.e. F=m x a is Force equals mass times acceleration... etc)

    These are basic stuff which you should have hammered home, very important...

    The syllabus should have a list of the equations which are not provided in the exam at the front. If you have a Lett's physics revision guide, then they are in the back of that too.

    If you're doing OCR, check out the syllabus. It is great for last-minute revision!

    I am not sure if we need to know formulae considering Area, Volume and Pressure, learn them just incase, they are:

    Pressure: P=F/A
    Area: P=F/A
    Volume: P1 x V1 = P2 x V2

    You know how to use the formula correctly, yeah?
    Ok, best way is to use a formula triangle...
    How to use a formula triangle:
    If the equation is A=BxC, then the triangle would be like this...
    A
    B|C (you want to find A, so cover up A and you are left with B|C or BxC)

    If you wanted to find B, in the same formula, u set the triangle out like so:
    A
    B|C (Cover up B and you're left with A / C)

    Also, if the equation is like this:
    A=B/C, then the triangle is like this:
    B
    A|C (Obviously B needs to be at the top so that it can be divided by something...)
    Then if u want to find C, you cover up C and are left with: B/A...)
    Simple Ask me if u need help.
