Isaac Newton Quotes

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

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

For every action there is an equal and opposite reaction.

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

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.

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.

To every action there is always opposed an equal reaction, or, the mutual actions of two bodies upon each other are always equal, and directed to contrary parts.

A point of rest alone explains motion.

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.

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.

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.

What goes up must come down.

It is just physics - who can argue with Newton and the first law of thermodynamics?

To every action there is always opposed an equal reaction.

Everything I do is somehow connected to velocity.

A moving body whose motion was not retarded by any resisting force would continue to move to all eternity.

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 universe is composed of matter, and, as a system, is sustained by motion. Motion is not a property of matter, and without this motion the solar system could not exist.

It is indeed a law of politics as well as of physics, that a body in action must overcome a body at rest.

Momentum solves 80% of your problems.

Gravity is more powerful where there's more stuff.

Give me a lever long enough and a fulcrum on which to place it, and I shall move the world.

For relaxation, I like to figure skate. Being on the ice and spinning and jumping, I feel very close to nature. In particular, I feel very close to Newton's laws of motion. On the ice, you can experience Newton's laws of motion in their purest, most elegant form.
