Newton's cannonball was a thought experiment Isaac Newton used to hypothesize that the force of gravity was universal, and it was the key force for planetary motion. It appeared in his posthumously published 1728 work De mundi systemate (also published in English as A Treatise of the System of the World). [1] [2]
Newton's cannonball is a thought experiment that interpolates between projectile motion and uniform circular motion. A cannonball that is lobbed weakly off the edge of a tall cliff will hit the ground in the same amount of time as if it were dropped from rest, because the force of gravity only affects the cannonball's momentum in the downward ...
After being appointed a lecturer in experimental philosophy at Hart Hall, Keill started giving lectures and performing experiments based on Newton's findings. He instructed his students on the laws of motion , the principles of hydrostatics and optics , and Newtonian propositions on light and colours.
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 ...
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.
Composed in 1669, [4] during the mid-part of that year probably, [5] from ideas Newton had acquired during the period 1665–1666. [4] Newton wrote And whatever the common Analysis performs by Means of Equations of a finite number of Terms (provided that can be done) this new method can always perform the same by means of infinite Equations.
Newton saw God as an intelligent, powerful, omnipresent Being which governs all. [6] It has been claimed that the text implies that Newton was an anti-Trinitarianist heretic . [ 7 ] With no comments explicitly addressing the subject of the Holy Trinity, several parts of the text seem to raise anti-Trinitarianist positions indirectly, most notably:
The generalized binomial theorem gives (+) = = = + + +.A proof for this identity can be obtained by showing that it satisfies the differential equation ...
