    Why torque?

    well, a good question. but it is a question not to be asked....first moment of inertia is a definition and definitions cant be put to questions...second you cant just consider one case to change a definition (just like you said it simplifies force eq)....for ex if you are done with the...

    yes i ment the same....if i am not rong when i read about the atom modal, people said that as any moving charged particle would lose energy and thus the negative charge would consequently fall down in the nucleus if not for the bhor's energy level...am i rite?

    Mechanics basics a big doubt !

    great ! i wanted this ans to pop out.. so now both A and B would see the other having centripetal forces in their respective reference frames rite?? for A B's Fcent = Mass of b * velocity(b)^2 / radius for B A's Fcent = Mass of a * velocity(a)^2 / radius since they are relative both the...

    Mechanics basics a big doubt !

    well, let us consider they are particles ( for simplicity ).....so thus there is no sense to talk about revolving...
