Instantaneous Speed and Macro-Rotational Wave Speed Determine the Properties of Positive and Negative Charge— Unified Derivation of Four Forces from the Instantaneous Speed of the World Quantum

Based on the World Quantum Theory (WQT) framework, the motion of particles is essentially a manifestation of the macro-rotation of world quanta. The instantaneous momentum of a world quantum can be defined as p=m(v(t)−v), where v(t) is the instantaneous tangential speed of the world quantum, and v is the particle's macro-rotational wave speed. This paper demonstrates that v(t) corresponds to the instantaneous speed of the world quantum at each instant, and v corresponds to the macro-rotational wave speed (the root-mean-square tangential speed). The difference v(t)−v determines the properties of positive and negative charge: when the instantaneous speed continuously deviates from the macro-rotational wave speed in an increasing manner, it manifests as positive charge; when it continuously deviates in a decreasing manner, it manifests as negative charge. Taking the time derivative of this momentum formula naturally yields a unified expression for the four forces — electric force, magnetic force, nuclear force, and gravitational force. This paper provides a self-consistent derivation of the nature of charge and the unification of forces.
