Isaac Newton Quotes

What goes up must come down.

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

Weight, force and casual impulse, together with resistance, are the four external powers in which all the visible actions of mortals have their being and their end.

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

In bodies moved, the motion is received, increased, diminished, or lost, according to the relations of the quantity of matter and velocity; each diversity is uniformity, each change is constancy.

Another mode of accumulating power arises from lifting a weight and then allowing it to fall.

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

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.

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

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

My physics teacher, Thomas Miner was particularly gifted. To this day, I remember how he introduced the subject of physics. He told us we were going to learn how to deal with very simple questions such as how a body falls due to the acceleration of gravity.

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.

Newman's first law: It is useless to put on your brakes when you're upside down.

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

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.

In order to lift a certain object from the ground, we have to use energy. But then to sustain it at that level, we have to keep on adding energy, or otherwise, the object falls to the ground. It's exactly the same thing with the sound.

We're used to thinking of force as a stable phenomenon, but it has a cinematic variable, which is acceleration.

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

Momentum solves 80% of your problems.

All great results in our universe are founded in motions and forces the most minute.

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.

Though we may never be able to comprehend human life, we know certainly that it is a movement, of whatever nature it be. The existence of movement unavoidably implies a body which is being moved and a force which is moving it. Hence, wherever there is life, there is a mass moved by a force. All mass possesses inertia; all force tends to persist.

The great weight of the ship may indeed prevent her from acquiring her greatest velocity; but when she has attained it, she will advance by her own intrinsic motion, without gaining any new degree of velocity, or lessening what she has acquired.

For every action there is an equal and opposite reaction.

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.
