Homework Help: I need some help with some formulas

  1. Feb 12, 2005 #1
    Explanation of what is what in the formula and the unit in which they are in.

    The force between two charges.

    The centrifugal force between two rotating masses.

    The r * r in that equation is it the radie or the diameter? I mean the length.


    The mass of light. There are two versions.

    Which one is right?

    mass = h planck konstant*f frequnsy
    ----------------------------
    c * c

    The planck konstant can be modified to be divided by 2pi.

    Should it? It would seem so if compared by the maximum mass a light photon can have.

    mass = h planck konstant*f frequnsy
    ----------------------------
    c * 2 * pi c


    Aslo the formula for an accelerating charge.

    Charged partickles with mass are atrakted to each other and I am going to do an computer simulation.
    How musch should the accelerating xyz be incremented per time unit?

    The smaller time period the smaller increment in their trajektories.

    F = something.

    A Acceleration = (mass1 +mass2 )*time* q1 * q2
    ------------------------------
    distans between them


    X led The acceleration is modified each interval in x and y and z led. +
    or minus a ceartain element.
    y led
    z led

    This acceleration x is then added to the x position of the partickle.
    This acceleration y is then added to the y position of the partickle.
    This acceleration z is then added to the z position of the partickle.

    Is this right?

    Have i forgotten something. Help is greatly apreciated.

    Christopher. :tongue:

    What do you mean by "the maximum mass a light photon can have"...?
    And where did u get that:
    "A Acceleration = (mass1 +mass2 )*time* q1 * q2
    ------------------------------
    distans between them


    "

    It looks terribly incorrect.

    Forget the spelling.It's something secundary.Looks like a mixing with German...And how does he add acceleration with distance...?
