Isaac Newton Motion Quotes & Sayings

The new discipline of physics could not proceed until Isaac Newton appropriated words that were ancient and vague - force, mass, motion, and even time - and gave them new meanings. Newton made these terms into quantities, suitable for use in mathematical formulas. Until then, motion (for example) had been just as soft and inclusive a term as information. — James Gleick

An object in motion tends to remain in motion along a straight line unless acted upon by an outside force. — Isaac Newton

Just as the system of the sun, planets and comets is put in motion by the forces of gravity, and its parts persist in their motions, so the smaller systems of bodies also seem to be set in motion by other forces and their particles to be variously moved in relation to each other and, especially, by the electric force. — Isaac Newton

The one as much as it advances that of the other. If a body impinge upon another, and by its force change the motion of the other, that body also (because of the equality of the mutual pressure) will undergo an equal change, in its own motion, towards the contrary part. — Isaac Newton

Billy coughed when the door was opened, and when he coughed he shit thin gruel. This was in accordance with the Third Law of Motion according to Sir Isaac Newton. This law tells us that for every action there is a reaction and opposite in direction.
This can be useful in rocketry. — Kurt Vonnegut

A Vulgar Mechanick can practice what he has been taught or seen done, but if he is in an error he knows not how to find it out and correct it, and if you put him out of his road he is at a stand. Whereas he that is able to reason nimbly and judiciously about figure, force, and motion, is never at rest till he gets over every rub.
(from a letter dated 25 May, 1694) — Isaac Newton

Resistance is usually ascribed to bodies at rest, and impulse to those in motion, but motion and rest, as commonly conceived, are only relatively distinguished; nor are those bodies always truly at rest, which commonly are taken to be so. — Isaac Newton

Outside the train, the world went by, and somewhere above him in the sky, a plane flew away, and objects in motion would stay in motion, and objects at rest would stay at rest. Isaac Newton -- the real one, the one Isaac had been named after -- had figured out that law, and a law wasn't a theory, it was a law. The air Rick had breathed out was still in Isaac's apartment, and the sheets still smelled like him, and there were little parts of him everywhere, and someday he'd come home, and against the great scale of universal time, a few months wasn't long at all. Before Isaac even knew it, they'd be together. The train would rock its way down the tracks and Rick's airplane would fly west and the planet would rotate and the solar system would turn and the galaxy would spin and the universe would keep on expanding, and with enough time, everything in it would again be made right. — Shukyou

An object that is at rest will tend to stay at rest. An object that is in motion will tend to stay in motion. — Isaac Newton

The birth of science as we know it arguably began with Isaac Newton's formulation of the laws of gravitation and motion. It is no exaggeration to say that physics was reborn in the early 20th-century with the twin revolutions of quantum mechanics and the theory of relativity. — Paul Davies

The alternation of motion is ever proportional to the motive force impressed; and is made in the direction of the right line in which that force is impressed. — Isaac Newton

So great a contribution to physics was Two New Sciences that scholars have long maintained that the book anticipated Isaac Newton's laws of motion. — Stephen Hawking

Do not Bodies and Light act mutually upon one another; that is to say, Bodies upon Light in emitting, reflecting, refracting and inflecting it, and Light upon Bodies for heating them, and putting their parts into a vibrating motion wherein heat consists? — Isaac Newton

The same law takes place in a system, consisting of many bodies, as in one single body, with regard to their persevering in their state of motion or of rest. For the progressive motion, whether of one single body or of a whole system of bodies, is always to be estimated from the motion of the center of gravity. — Isaac Newton

Pictures, propagated by motion along the fibers of the optic nerves in the brain, are the cause of vision. — Isaac Newton

Heron of Alexandria! I've never read his treatise on pneumatics and hydraulics!" (Kate) cried in excitement.
"What luck."
She barely heard (Rohan)'s droll comment, gasping aloud when she spotted the rarest of tomes. "You have Al-Jazari's Book of Knowledge of Ingenious Mechanical Devices?"
"Do I?"
"I don't believe it! Is this the original fourteenth-century Latin translation from the Arabic?"
"Couldn't tell you."
She handled the aged manuscript with awe. "You mean you haven't read it?"
"Alas."
"Oh, Rohan! Sir Isaac Newton wouldn't have been able to formulate the laws of motion if it weren't for writers like this. — Gaelen Foley

I can calculate the motion of heavenly bodies but not the madness of people. — Isaac Newton

There was yet another disadvantage attaching to the whole of Newton's physical inquiries, ... the want of an appropriate notation for expressing the conditions of a dynamical problem, and the general principles by which its solution must be obtained. By the labours of LaGrange, the motions of a disturbed planet are reduced with all their complication and variety to a purely mathematical question. It then ceases to be a physical problem; the disturbed and disturbing planet are alike vanished: the ideas of time and force are at an end; the very elements of the orbit have disappeared, or only exist as arbitrary characters in a mathematical formula. — George Boole

A body in motion tends to stay in motion unless acted on by an outside force. — Isaac Newton

As to your Newton, I confess I do not understand his void and his gravity; I admit he has demonstrated the movement of the heavenly bodies with more exactitude than his forerunners; but you will admit it is an absurdity to maintain the existence of Nothing.
[Letter to Voltaire, 25 Nov. 1777] — Frederick The Great

Gravity may put the planets into motion, but without the divine Power, it could never put them into such a circulating motion as they have about the Sun; and therefore, for this as well as other reasons, I am compelled to ascribe the frame of this System to an intelligent Agent. — Isaac Newton

Every body persists in a state of rest or of uniform motion in a straight line, unless it is compelled to change that state by forces having impact upon it. — Isaac Newton

To derive two or three general Principles of Motion from Phaenomena, and afterwards to tell us how the Properties and Actions of all corporeal Things follow from those manifest Principles, would be a very great step in Philosophy. — Isaac Newton

Are not all Hypotheses erroneous, in which Light is supposed to consist in Pression or Motion, propagated through a fluid Medium? For in all these Hypotheses the Phaenomena of Light have been hitherto explain'd by supposing that they arise from new Modifications of the Rays; which is an erroneous Supposition. — Isaac Newton

It may be that there is no such thing as an equable motion, whereby time may be accurately measured. All motions may be accelerated or retarded, but the true, or equable, progress of absolute time is liable to no change. — Isaac Newton

I do not define time, space, place, and motion, as being well known to all. Only I must observe, that the common people conceive those quantities under no other notions but from the relation they bear to sensible objects. And thence arise certain prejudices, for the removing of which it will be convenient to distinguish them into absolute and relative, true and apparent, mathematical and common. — Isaac Newton

Chickens at rest tend to stay at rest. Chickens in motion tend to cross roads. — Isaac Newton

Long ago, Sir Isaac Newton gave us three laws of motion, which were the work of genius. But Sir Isaac's talents didn't extend to investing: He lost a bundle in the South Sea Bubble, explaining later, I can calculate the movement of the stars, but not the madness of men. If he had not been traumatized by this loss, Sir Isaac might well have gone on to discover the Fourth Law of Motion: For investors as a whole, returns decrease as motion increases. — Warren Buffett

Very few of us can now place ourselves in the mental condition in which even such philosophers as the great Descartes were involved in the days before Newton had announced the true laws of the motion of bodies. — James Clerk Maxwell

When asked about which scientist he'd like to meet, Neil deGrasse Tyson said, Isaac Newton. No question about it. The smartest person ever to walk the face of this earth. The man was connected to the universe in spooky ways. He discovered the laws of motion, the laws of gravity, the laws of optics. Then he turned 26. — Neil DeGrasse Tyson

The same thing is to be understood of all bodies, revolved in any orbits. They all endeavour to recede from the centres of their orbits, and were it not for the opposition of a contrary force which restrains them to and detains them in their orbits, which I therefore call Centripetal, would fly off in right lines with a uniform motion. — Isaac Newton

Gravity explains the motions of the planets, but it cannot explain who sets the planets in motion. — Isaac Newton

One [method] is by a Watch to keep time exactly. But, by reason of the motion of the Ship, the Variation of Heat and Cold, Wet and Dry, and the Difference of Gravity in different Latitudes, such a watch hath not yet been made. — Isaac Newton

If a projectile were deprived of the force of gravity, it would not be deflected toward the earth but would go off in a straight line into the heavens and do so with uniform motion, provided that the resistance of the air were removed. — Isaac Newton

When Isaac Newton embarked on his great program, he encountered a fundamental lack of definition where it was most needed. He began with a semantic sleight of hand: "I do not define time, space, place, and motion, as being well known to all," he wrote deceptively. Defining these words was his very purpose. There were no agreed standards for weights and measures. Weight and measure were themselves vague terms. Latin seemed more reliable than English, precisely because it was less worn by everyday use, but the Romans had not possessed the necessary words either. — James Gleick

I can measure the motion of bodies but I cannot measure human folly. — Isaac Newton

The moon gravitates towards the earth and by the force of gravity is continually drawn off from a rectilinear motion and retained in its orbit. — Isaac Newton

The great Sir Isaac Newton, He once made a valid proclamation, That the forces equal to a nominated mass, when multiplied by acceleration That was the law of motion. — Richard Digance

Ax: 100 Every thing doth naturally persevere in yt state in wch it is unlesse it bee interrupted by some externall cause, hence ... [a] body once moved will always keepe ye same celerity, quantity & determination of its motion. — Isaac Newton
