Work energy method and impulse momentum method

  1. Oct 2, 2005 #1
    we have two concepts

    1)if force is applied for a distance x(i.e work) it increases the kinetic energy of a mass

    2)if force is applied for a time t(i.e impulse) it increases the momentum of the mass

    why there are two concepts. Are the above two same?

    Neither of those things you just said are correct. Work and kinetic energy are not the same thing and impulse and momentum are not the same thing either.
