Motion of planets around the sun is not circular, even though sun is the central force causing planets to move (Refer previous mantra 10.149.1) 2. The motion of planets is such that Velocity of planets is in inverse relation with the distance between planet and sun. It can be easily shown with the help of Newton’s Second Law that, for a planet revolving around sun in an elliptical orbit, having distance ‘r’ with sun and angle ‘θ’ made between length ‘r’ and any fixed axis, at any instant, following holds true From the above, it can be easily shown that derivative of the product of square of distance between sun and planet and rate of change of angle θ, with respect to time, is zero. And thus following relation is obtained (with h as a constant)
'Gravity is the Force that appears to attract Physical Bodies towards each other'. Let's see how much we know about it. Note the Definition, 'appears to attract' - We are not sure. Einstein's Views -'Theory of General Relativity' as applied to Gravity. Space and Time , Spacetime condition Gravity.

Isaac Newton demeure l'une des énigmes de la Science. Il était un scientifique par excellence. Sir Isaac Newton, mais contrairement à certains autres scientifiques, qu'il croyait à l'intuition, avec raison. Pas pour lui, la rhétorique vide de la "seule raison' Il était un chercheur de vérité, comment il avait obtenu leur a été d'aucune préoccupation … Continue reading Isaac Newton Scientifique,Sorcier ou Noetic Scientifique?
To me he was a Noetic Scientist of the first order.
