A body in motion can maintain this motion only if it remains in contact with a mover.

“They who are to be judges must also be performers.”
“We praise a man who feels angry on the right grounds and against the right persons and also in the right manner at the right moment and for the right length of time.”
“And inasmuch as the great-souled man deserves most, he must be the best of men; for the better a man is the more he deserves, and he that is best deserves most. Therefore the truly great-souled man must be a good man. Indeed greatness in each of the virtues would seem to go with greatness of soul.”

“The Prussian Academy of Sciences is a fast-track academic institute that requires a proactive, hands-on-type individual to overthrow the Newtonian conception of the universe. The successful candidate will have an excellent command of mass, energy, space, time and some maths. Bonus paid upon completion of proofs”
“Physics is really figuring out how to discover new things that are counterintuitive, like quantum mechanics. It's really counterintuitive.”
“...The entire preoccupation of the physicist is with things that contain within themselves a principle of movement and rest.”
More on Motion
“Every little bit, every atom inside the universe, is in a constant state of change and motion, but the universe as a whole is unchangeable, because motion or change is a relative thing; we can only think of something in motion in comparison with something which is not moving.”
“There is no motion in a straight line. A straight line infinitely projected becomes a circle.”
“We, on the other hand, must take for granted that the things that exist by nature are, either all or some of them, in motion.”
