Is it appropriate to say that within classical physics the general form of Newton II is the Cauchy momentum equation?
This equation applies to an arbitrary continuum body. Therefore it is more general than the common form of Newton II which applies basically to point masses and centers of mass of rigid bodies only. However, I haven't heard anyone referring to the Cauchy momentum equation as the general form of Newton II.
