This is a general physical law derived from empirical observations by what Isaac Newton called inductive reasoning. [4] It is a part of classical mechanics and was formulated in Newton's work Philosophiæ Naturalis Principia Mathematica ("the Principia"), first published on 5 July 1687. The equation for universal gravitation thus takes the form:
In the history of physics, hypotheses non fingo (Latin for "I frame no hypotheses", or "I contrive no hypotheses") is a phrase used by Isaac Newton in the essay General Scholium, which was appended to the second edition of Philosophiae Naturalis Principia Mathematica in 1713.
The concepts invoked in Newton's laws of motion — mass, velocity, momentum, force — have predecessors in earlier work, and the content of Newtonian physics was further developed after Newton's time. Newton combined knowledge of celestial motions with the study of events on Earth and showed that one theory of mechanics could encompass both.
Sir Isaac Newton (/ ˈ nj uː t ən /; 25 December 1642 – 20 March 1726/27 [a]) was an English polymath active as a mathematician, physicist, astronomer, alchemist, theologian, and author. [5] Newton was a key figure in the Scientific Revolution and the Enlightenment that followed. [ 6 ]
Portrait of Sir Isaac Newton (1643–1727), author of the Principia, by Godfrey Kneller (1689). The Preface of the work states: [15]Rational Mechanics will be the sciences of motion resulting from any forces whatsoever, and of the forces required to produce any motion, accurately proposed and demonstrated ...
Sir Isaac Newton (1643–1727), an influential figure in the history of physics and whose three laws of motion form the basis of classical mechanics Newton founded his principles of natural philosophy on three proposed laws of motion : the law of inertia , his second law of acceleration (mentioned above), and the law of action and reaction ...
Later, in 1686, when Newton's Principia had been presented to the Royal Society, Hooke claimed from this correspondence the credit for some of Newton's content in the Principia, and said Newton owed the idea of an inverse-square law of attraction to him – although at the same time, Hooke disclaimed any credit for the curves and trajectories ...
