Is the weak force really a "force"? I have seen that gravity, electromagnetism and the strong force are described by physicists in detail in the sense that specific things can be said about what is attracted and/or repulsed and under what circumstances these forces are manifested. All we ever seem to see about the weak force is that it is responsible for some phenomena like beta decay and it is mediated by the W and Z bosons. But what is it? Is it attractive? Is it repulsive? Is it sideways? Is it sometimes repulsive and sometimes attractive like electric charge? Is that why it is mediated by two types of bosons? What particles are effected by this force? Is it really a "force" in the sense that particles can be caused to move as in F = ma?
