There is no science in this world like physics. Nothing comes close to the precision with which physics enables you to understand the world around you. It's the laws of physics that allow us to say exactly what time the sun is going to rise. What time the eclipse is going to begin. What time the eclipse is going to end.
I am a figure skater, which helps me appreciate Newton's theory of mechanics.
Physics is experience, arranged in economical order.
... everything in the world is a force, a pull or a push. In order for us to be pushed or pulled we need to be like a sail, like a kite in the wind. But if we have a hole in the middle of our luminosity, the force goes through it and never acts upon us.
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.
Newton's great generalization, which he called the "third law of motion," was that "Action and reaction are always equal to each other;" and that law has been one of the most pregnant of all truths about the mystery of force;--one of the brightest windows through which modern eyes have looked into the world of Nature.
I love physics because it's neat and it's orderly in its own peculiar way.
If the apple hit Newton’s nose, Newton’s nose hit the apple.
Physics is the most basic part of science and, of course, math. It gives you insight into everything - a foundation, I should say, to understand nature and the universe.
Children need to be exploring their physical world. They need to be learning the fundamental laws of physics by manipulating objects.
Newton came up with Newton's laws of motion and gravity. They worked. They were working.
Impressed force is the action exerted on a body to change its state either of resting or of moving uniformly straight forward.
...The entire preoccupation of the physicist is with things that contain within themselves a principle of movement and rest.
Any schoolboy could see that man as a force must be measured by motion, from a fixed point.
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.
Effort supposes resistance.
The light works," he said, indicating the window, "the gravity works," he said, dropping a pencil on the floor. "Anything else we have to take our chances with.
Mechanics is the paradise of the mathematical sciences because by means of it one comes to the fruits of mathematics.
Motion is created by the destruction of balance.
Physics is, hopefully, simple. Physicists are not.
Physics is nothing but the ABC's. Nature is an equation with an unknown, a Hebrew word which is written only with consonants to which reason has to add the dots.
Bowling is all physics and energy distribution. It's F = ma. So it is actually one of the most science-y sports, because it literally is just a ball and a surface and objects to knock down.
Archimedes had stated, that given the force, any given weight might be moved; and even boasted that if there were another earth, by going into it he could remove this.
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.
