In this work, we develop a deterministic physical model of force, gravitation, and weight based on microscopic imbalances between positive (+) and negative (—) charge units. Within the proposed framework, energy deficiency in negative charge units generates a fundamental attractive interaction with positive charge units, leading to an effective microscopic force that scales approximately as r −3 with distance. Through statistical averaging of this microscopic interaction in many-body systems, the emergence of gravitation at macroscopic scales is obtained. The model further demonstrates that the mutual attraction between a material object and a celestial body, in which both bodies exert equal and opposite forces on each other, manifests as weight through their combined effect. Accordingly, weight is interpreted as the resultant of reciprocal gravitational responses between interacting bodies. The proposed theory treats force, gravitation, and weight not as independent phenomena, but as different manifestations of a single underlying microscopic mechanism. The mathematical framework preserves dimensional consistency and predicts measurable deviations in high-density systems and microscopic structures. These predictions are experimentally testable and provide an alternative perspective on the microscopic origin of gravitational interactions.
