Despite being a simple concept of force as an emergent phenomenon through mechanical formation, it is as profound as a force resulting from the counterintuitive random Brownian motions of degrees of freedom. This means Brownian motions of matter in a medium are justified by allocating space filled with degrees of freedom. Our question is, what is the resulting emergent force that causes the Brownian motion of those degrees of freedom? We have two answers: 1) It is either formed by some other unknown degrees of freedom, presumably, even smaller than degrees of freedom that contribute predominantly to interactive forces of matter. 2) The universe is working like a mechanical cycle similar to a machine such as a mechanical watch. The second hypothesis is relatively intuitive compared with the first hypothetical solution as we can stop at a minimum size of a degree of freedom as inferred from quantum theory. Consequently, one does not need to go to infinitesimal sizes to fully understand the mechanism of force formation. However, the imagination of such a system to systematically explain the mechanical force among all degrees of freedom is extremely difficult.
