The Gravitational Force Quantum and its Value

Gravitation is one of basic phenomena of world. Tremendous number of theoretical works on origin, nature, essentials, consequences, etc. of gravitation and related phenomena were published so far. The most prominent ones are based on Albert Einstein's general theory of relativity. The author of this communication based his approach to gravitation on Isaac Newton's law of universal gravitation and related quantities, i.e. gravitational forces of matter objects, distance and motion. Namely on fact, that gravitation force is - as well as inertia, mass, space occupied and other properties are - principal features/attributes/properties of matter objects. Gravitation is an additive property of matter objects. Taking into account other positivistic quantities like mass of Earth, standard acceleration of gravity, and value of atomic unit of mass, author defined a gravitational force of atomic unit (or the Gravitational Force Quantum) as a gravitational force which exerts one atomic unit of Earth's mass on 1 kilogram of a mass on Earths surface, and he calculated its value: GFO = 1.4958 × 10 -54 N. This quantity can be useful for further development of quantum mechanical approach to description and general notion about world.
