The model of gravity based on the nuclear kinetic dipole states that each atomic nucleus constantly generates a pushing force which imparts a linear momentum to the atom. The direction of that force can be changed through gravitational polarization, a macroscopic body being pushed from within in the direction of surrounding bodies by the cumulative force of its nuclei. The pushing force of a single nucleon is thought to be the gravitational force quanta, its value being derived from the Avogadro program for a new definition of the kilogram. The gravitational force quanta is found to be ≈ 2 x 10-19 a.u. (atomic unit of force) which could be confirmed through a proposed experiment. An alternative definition of the kilogram is also proposed, along with multiple possibilities to build kilogram etalons. Particularly, subdivisions of the kilogram (e.g. gram, milligram, microgram) can be accurately reproduced onsite through nano-3D printing for the purpose of calibrating high-precision scales and balances.
