Type of force

    i know there are gravitational and friction force.
    can anyone tell me names of forces other than those?

    Are we talking about fundamental forces here? If so there are only four and they account for all interactions currently observed and are as follows; Gravity, Weak Nuclear, Strong Nuclear and Electromagnetic.

    This is true, but for the sake of clarity, there's a slight correction to be made. We seldom attrach the word "nuclear" to both the weak and strong interactions. This is because they don't just have to interact with "nuclear" particles. Neutrinos, for example, are not nucleons, and they only interact via the weak interactions (that's why they could pass through the earth very easily). The strong force could possibly be mainly for "nucleons", but they are really generally an interaction for hadrons, which also includes mesons in addition to baryons.

    Could catch:smile: I'll drop the 'nuclear' in future.

    I don't know if this counts in the context of the question, but there are also Van der Waals force, electrostatic, torsional, etc.. Those, of course, are offshoots of the main 4.

    edit: Never mind torsional, since I suppose that it's just a different way of looking at torque.

    I think it's time for the OP to step up to the plate and tell us exactly what (s)he is after.
