Isaac Newton Quotes

We know there is gravity because apples fall from trees. We can observe gravity in daily life. If we could throw an apple to the edge of the universe, we would observe it accelerating.

I love physics.

Gravity is a habit that is hard to shake off.

Physics has the cutest words.

Gravity is more powerful where there's more stuff.

I like physics. I think it is the best science out of all three of them, because generally it's more useful. You learn about speed and velocity and time, and that's all clever stuff.

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.

You can't argue with physics, mate.

Gravity is more suggestive than convincing.

Galileo had already made a significant beginning toward a knowledge of the law of motion. He discovered the law of inertia and the law of bodies falling freely in the gravitational field of the earth.

Weight is caused by one element being situated in another; and it moves by the shortest line towards its centre, not by its own choice, not because the centre draws it to itself, but because the other intervening element cannot withstand it.

Gravity is matter’s sugar daddy.

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

Not believing in force is the same as not believing in gravity.

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

Everything I do is somehow connected to velocity.

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

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

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.

Gravity wins over all other known forces.

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

The moon gravitates towards the earth and by the force of gravity is continually drawn off from a rectilinear motion and retained in its orbit.

Black holes are very exotic objects. Technically, a black hole puts a huge amount of mass inside of zero volume. So our understanding of the center of black holes doesn't make sense, which is a big clue to physicists that we don't have our physics quite right.

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.
