Physics deals with a wide variety of systems, although certain theories are used by all physicists. Each of these theories was experimentally tested numerous times and found to be an adequate approximation of nature. For instance, the theory of classical mechanics accurately describes the motion of objects, provided they are much larger than atoms and moving at a speed much less tha… WebbAcceptance rate *. 68%. *Acceptance rate is calculated as acceptance decisions as a proportion of all final decisions on directly submitted articles.
