By such deductions the law of gravitation is rendered probable, that every particle attracts every other particle with a force which varies… — Isaac Newton Copy Share Image
God is able to create particles of matter of several sizes and figures and perhaps of different densities and forces, and thereby… — Isaac Newton Copy Share Image
Our present work sets forth mathematical principles of philosophy. For the basic problem of philosophy seems to be to discover the forces… — Isaac Newton Copy Share Image
A body in motion tends to stay in motion unless acted on by an outside force. — Isaac Newton Copy Share Image
I have explained the phenomena of the heavens and of our sea by the force of gravity, but I have not yet… — Isaac Newton Copy Share Image
Centripetal force is the force by which bodies are drawn from all sides, are impelled, or in any way tend, toward some… — Isaac Newton Copy Share Image
Every body persists in a state of rest or of uniform motion in a straight line, unless it is compelled to change… — Isaac Newton Copy Share Image
The alternation of motion is ever proportional to the motive force impressed; and is made in the direction of the right line… — Isaac Newton Copy Share Image
Impressed force is the action exerted on a body to change its state either of resting or of moving uniformly straight forward. — Isaac Newton Copy Share Image
Bullialdus wrote that all force respecting ye Sun as its center & depending on matter must be reciprocally in a duplicate ratio… — Isaac Newton Copy Share Image
I have presented principles of philosophy that are not, however, philosophical but strictly mathematical-that is, those on which the study of philosophy… — Isaac Newton Copy Share Image
Every particle of matter is attracted by or gravitates to every other particle of matter with a force inversely proportional to the… — Isaac Newton Copy Share Image
Qu. 31. Have not the small Particles of Bodies certain Powers, Virtues or Forces, by which they act at a distance, not… — Isaac Newton Copy Share Image
Thus far I have explained the phenomena of the heavens and of our sea by the force of gravity, but I have… — Isaac Newton Copy Share Image
Definition of inertia: 'The vis insita, or innate force of matter, is a power of resisting by which every body, as much… — Isaac Newton Copy Share Image
An object in motion tends to remain in motion along a straight line unless acted upon by an outside force. — Isaac Newton Copy Share Image
“In the beginning of the year 1665 I found the Method of approximating series & the Rule for reducing any dignity of… — Isaac Newton Copy Share Image
A Vulgar Mechanick can practice what he has been taught or seen done, but if he is in an error he knows… — Isaac Newton Copy Share Image
The same law takes place in a system, consisting of many bodies, as in one single body, with regard to their persevering in their… — Isaac Newton Copy Share Image
I have been much amused at ye singular phenomena resulting from bringing of a needle into contact with a piece of amber or resin… — Isaac Newton Copy Share Image
I keep the subject of my inquiry constantly before me, and wait till the first dawning opens gradually, by little and little, into a… — Isaac Newton Copy Share Image
Philosophy is such an impertinently litigious lady that a man had as good be engaged in lawsuits as have to do with her. — Isaac Newton Copy Share Image
Do not Bodies act upon Light at a distance, and by their action bend its Rays; and is not this action (caeteris paribus) [all… — Isaac Newton Copy Share Image
God in the beginning formed matter in solid, massy, hard, impenetrable, movable particles, of such sizes and figures, and with such other properties, and… — Isaac Newton Copy Share Image
I am ashamed to tell you to how many figures I carried these calculations [of Pi], having no other business at the time — Isaac Newton Copy Share Image
Blind metaphysical necessity, which is certainly the same always and every where, could produce no variety of things. All that diversity of natural things… — Isaac Newton Copy Share Image
You sometimes speak of gravity as essential and inherent to matter. Pray do not ascribe that notion to me, for the cause of gravity… — Isaac Newton Copy Share Image
