Motion, Physics, Metaphysics

Modern Physics is the study of the quantification of Locomotion, the fundamental unit of which is Velocity, on the basis of which Acceleration, and, thus, Force, is defined.  The concept of Velocity is that of the average change of Distance of Motion over a period of Time, and the concept of Acceleration is that of the average change of Velocity over a period of Time.  Thus, in Modern Physics, Continuity of Motion is only approximated to, e. g. as change of Time approaches Zero.  But concrete Motion is continuous, so the inadequacy to it in Physics is due to Quantification, constituted by discrete Quanta.  So, the study of the Continuity of Motion is not Modern Physics.  Instead, probably the only alternative that has been proposed has been by Bergson--Metaphysics.  Now, the apparent peculiarity of that characterization is derived from the common use of the term as connoting a Super-Natural realm.  But if Dualism is rejected, then pure Motion can be conceived as immanent, and so, too, can be Continuity of Motion, and, thus, unquantified Force.  Now, the subject of Motion is Matter, so Spinoza's concept of Proximate Cause, in which Matter, e. g. ink on a surface, is caused to change location, can be classified as Immanent Metaphysics.
