Relativ strength of all 4 forces

  1. Feb 4, 2012 #1
    I have a poor physics book that doesn't really explain things easy. My book states that

    Strong force - 1
    Electromagnetic force - 10^-2
    Weak force - 10^-6
    Gravity - 10^-43

    This is the "relative strength between the 4 forces" is what my book says.

    But what does that mean? Is there some maximum amount of gravity, which always is lower than the maximum amount of strong force. (it might be a very stupid question)

    hi johann1301! :smile:

    i think it's comparing the strengths of the different forces between the same pair of particles …

    eg the electromagnetic force between two electrons is about 1041 times the gravitational force between them
