Isaac Newton Quotes

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.

Every body continues in its state of rest or uniform motion in a straight line, except insofar as it doesn't.

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

A point of rest alone explains motion.

Momentum,' She repeats. 'You can't just stand there if you want something to fly. You have to run.

Any schoolboy could see that man as a force must be measured by motion, from a fixed point.

If your position is everywhere, your momentum is zero.

The natural law of inertia: Matter will remain at rest or continue in uniform motion in the same straight line unless acted upon by some external force.

Acceleration is finite, I think according to some laws of physics.

If you move something 10 pounds through space and then stop suddenly, there's a little overshoot. When you transfer weight from one leg to another, there's a certain way that it happens.

Playgrounds are essentially machines to induce Newtonian physics on our own bodies.

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.

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.

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.

For the elements have the property of moving back to their place in a straight line, but they have no properties which would cause them to remain where they are, or to move otherwise than in a straight line. The rectilinear motions of these four elements when returning to their original place are of two kinds, either centrifugal, viz., the motion of the air and the fire; or centripedal, viz., the motion of the earth, and the water; and when the elements have reached their original place, they remain at rest.

Words may move, but they're never moving fast enough.

Definition of inertia: 'The vis insita, or innate force of matter, is a power of resisting by which every body, as much as in it lies, endeavours to preserve its present state, whether it be of rest or of moving uniformly forward in a straight line.

I figured it out eventually," she says. She's sitting on the edge of the gurney again; her features slowly materialize as my vision clears. "It's momentum." "What?" I whisper. The feeling returning to my lips, spreading out to my fingertips and toes. "Momentum," she repeats. "You can't just stand there if you want something to fly. You have to run.

Every description of natural processes must be based on ideas which have been introduced and defined by the classical theory.

Anytime you hit a curve, or you hit on the side of the wall, you hit against the side of the sled. We're taking four to five, sometimes six or seven Gs on our body every time we go down the track. And then the crashing.

Our annual school physics trip was always to Blackpool Pleasure Beach, as it's such a good example of Newtonian physics. You can learn about centrifugal force and Newton's first law from the roller coasters, and the Viking long boat is a giant pendulum. It's good for children to understand that science underpins all these brilliant things.

I know all we're doing is travelling without moving. Speed freak faster than a speedin' bullet, slow down. If I don't, I might just lose it, locked up. You've got me honey, locked up under heavy brakin', yeah. You know I've got to hang on, drive too fast, I might be last.

For the world is movement, and you cannot be stationary in your attitude toward something that is moving.

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.

It was more work than it seemed, looking through a telescope, as the Earth was continually moving and you had to move along with it. You don't realize how fast this acutally happens, and it's kind of both creepy and wonderful when you stop to think about it. And it makes you realize there's absolutely no way to avoid change. You can sit there and cross your arms and refuse it, but underneath you, things are still spinning away.
