Two so far partially used alternative basic sets -algebraic relations and central laws -are completed and related with the standard differential equations. The senses and ranges of validities of all the equations are examined. The dual conception of the two fields is gradually transferred into the scientific system of radial -static, transverse -kinetic, and longitudinal -dynamic elementary forces, dependent on mutual distance, simultaneous motion and acceleration of interacting charges.
