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

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.
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.
Definition of inertia: 'The vis insita, or innate force of matter, is a power of resisting by which every body, as much as in it lies, endeavours to preserve its present state, whether it be of rest or of moving uniformly forward in a straight line.
For the elements have the property of moving back to their place in a straight line, but they have no properties which would cause them to remain where they are, or to move otherwise than in a straight line. The rectilinear motions of these four elements when returning to their original place are of two kinds, either centrifugal, viz., the motion of the air and the fire; or centripedal, viz., the motion of the earth, and the water; and when the elements have reached their original place, they remain at rest.
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.
How many of you have had a crush on a teacher? I mean, remember that Physics professor? Law One is so steamy, I'm getting worked up just thinking about it: Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it. Mee-yow.
I do not believe in eternal progress, that we are growing on ever and ever in a straight line. It is too nonsensical to believe. There is no motion in a straight line. A straight line infinitely projected becomes a circle. The force sent out will complete the circle and return to its starting place.
He who is ignorant of Motion, says Aristotle , is necessarily ignorant of all natural things. ...Not only was he entirely in the dark respecting the Laws, he was completely wrong in his conception of the nature of Motion. ...He thought that every body in motion naturally tends to rest.
There is no motion in a straight line. A straight line infinitely projected becomes a circle.
If a projectile were deprived of the force of gravity, it would not be deflected toward the earth but would go off in a straight line into the heavens and do so with uniform motion, provided that the resistance of the air were removed.
An object in motion tends to remain in motion along a straight line unless acted upon by an outside force.
In a certain sense you deny the existence of this world. You explain life as a state of rest, a state of rest in motion.
When you are in the line of your duty, it is like standing in front of a line of posts, and every post is in line. But step one step aside, and every post looks as though it were not quite in line. The farther you get away from that straight line, the more crooked the posts will appear. It is the straight and narrow path of duty that will lead you and me back to the presence of God.
Maybe time is nothing at all like a straight line. Perhaps it's shaped like a twisted doughnut. But for tens of thousands of years, people have probably been seeing time as a straight line that continues on forever. And that's the concept they based their actions on. And until now they haven't found anything inconvenient or contradictory about it. So as an experiential model, it's probably correct.
Each ray of light moves in the coordinate system 'at rest' with the definite, constant velocity V independent of whether this ray of light is emitted by a body at rest or a body in 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.
