The Lunar orbit paradox


Aleksandar S. Tomić




Newton's formula for gravity force gives greather force intensity for atraction of the Moon by the Sun than atraction by the Earth. However, central body in lunar (primary) orbit is the Earth. So appeared paradox which were ignored from competent specialist, beacause the most important problem, determination of lunar orbit, was inmediately solved sufficiently by mathematical ingeniosity – introducing the Sun as dominant body in the three body system by Delaunay, 1860. On this way the lunar orbit paradox were not canceled. Vujičić made a owerview of principles of mechanics in year 1998, in critical consideration. As an example for application of corrected procedure he was obtained gravity law in some different form, which gave possibility to cancel paradox of lunar orbit. The formula of Vujičić, with our small adaptation, content two type of acceleration – related to inertial mass and related to gravity mass. So appears carried information on the origin of the Moon, and paradox cancels.
