Conservation of Momentum Quotes

For every action there is an equal and opposite reaction.

Even before string theory, especially as physics developed in the 20th century, it turned out that the equations that really work in describing nature with the most generality and the greatest simplicity are very elegant and subtle.

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

To any action there is always an opposite and equal reaction; in other words, the actions of two bodies upon each other are always equal and always opposite in direction.

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.

I am a figure skater, which helps me appreciate Newton's theory of mechanics.

They're hitting harder now more than ever. The only person who would argue that is someone who has never had a physics class. They're faster and stronger, so the reality is the collisions have to be bigger.

It always seems odd to me that the fundamental laws of physics, when discovered, can appear in so many different forms that are not apparently identical at first, but, with a little mathematical fiddling, you can show the relationship.

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

To every action there is always opposed an equal reaction.

Momentum solves 80% of your problems.

But be very, very careful, because when you're playing with momentum, you're playing with fire.

Although the theory of relativity makes the greatest of demands on the ability for abstract thought, still it fulfills the traditional requirements of science insofar as it permits a division of the world into subject and object (observer and observed) and, hence, a clear formulation of the law of causality.

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.

It's not magic! It's physics. The speed of the turn is what keeps you upright. It's like a spinning top.

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

Symmetry principles are principles governing the laws of nature that say those laws look the same if you change your point of view in certain ways.

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.

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

Physics is based on the assumption that certain fundamental features of nature are constant.

Physics has a history of synthesizing many phenomena into a few theories.

We have no right to assume that any physical laws exist, or if they have existed up until now, that they will continue to exist in a similar manner in the future.

Physics without mathematics is meaningless.

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

What physics tells us is that everything comes down to geometry and the interactions of elementary particles. And things can happen only if these interactions are perfectly balanced.
