Aug 20 revised How can Kinetic energy formula and the Work formula be derived without assuming the other to be true? edited body Aug 20 comment How can Kinetic energy formula and the Work formula be derived without assuming the other to be true? I suppose what you want to know is something along the lines of, "What motivated people to come up with that definition of work in the first place?" I don't know, but that's a different question than the one I was answering, which was an accusation that the logic is circular. Aug 20 comment How can Kinetic energy formula and the Work formula be derived without assuming the other to be true? I fixed a mistake in the derivation. I'm not sure what you're asking for with "how do we know the work formula"? I am taking that as the definition of work.
