In this paper the relationship between the Plancks constant and Einsteins gravitational constant is derived. The relationship between the Plancks constant and Newtons gravitational constant is derived. The relationship between the Plancks constant and the electric force of 1 Coulomb and magnetic force of 1 Henry is derived. It is shown that the Planck constant is the density of the momentum of the empty space of the universe. It is shown, that the force of gravity has its opposite strength counterpoint in the internal momentum of atomic particles of bodies. It is shown, that nature does not know two quantities of matter the mass and electric charge and does not know several forces like gravitational, electric, magnetic forces introduced by man. It is shown, that in nature, there is only one kind of force what is the force balance of inertial forces between internal momentum of particles oriented opposite with the power of its own force field around particles. In this paper it is claimed, that the essence of the composition of all atomic particles of bodies as well as of all force fields in the universe is the same and it is compressions of density of momentum of the empty space of the universe.
