Physics, Radiality, Direction

According to Kant's representation of Newtonian Physics, every motion consists of Velocity and Direction.  However, the direction of radial motion seems unclear.  For, if, as Kant describes one example of that motion, expansion, which is caused by repulsion from within, a body "endeavors to extend itself everywhere", "on all sides", then he implies that it moves in all directions at once.  However, a multiplicity of directions would seem to imply a multiplicity of motions, not one.  Rather, omnidirectionality is itself derived from a pre-directional radial encompassing of all directions.  In other words, Direction is abstracted from Radiality.  Now, oriented Space, e. g. experiential space, is self-evidently radial.  Thus, Kantian Space, which is oriented, is the a priori ground of Newtonian Directionality, as has been previously proposed here.
