...motion that govern all material bodies and which are also relevant to flight: • A body will continue in its state of rest, or uniform motion in a straight line, unless acted on by an external force. Put another way, an object at rest (or in motion) will remain...

...Statics—The whole subject of statics, that part of mechanics dealing with bodies in equilibrium, is based on Newton's first law: “Every body continues in its...state of rest or uniform motion in a straight line unless acted upon by an outside force.” The corollary of this: “If any unbalanced force acts upon...

...And as we now point out, that date is much closer than most people seem to think. 5 Going Critical Every body continues in its state of rest or uniform motion in a straight line, except insofar as it doesn't. — Sir Arthur Eddington, father of astrophysics The End Game Determining when...

...motion concern inertia, acceleration and actionreaction. The Law of Inertia (First Law) states that every body continues in its state of rest or uniform motion in a straight line except when it is compelled by external forces to change its state. The Law of Acceleration (Second Law) states...

...us consider the following three laws of motion, known as Newton mechanics, 1. Every body perseveres in its state of rest, or uniform motion in a straight line, except in so far as it is compelled to change that state by forces impressed on it (this law is regarded as...

...clear that the mere existence of runaways does not contradict to Newton's first law ('every particle continues in its state of rest or uniform motion in a straight line unless it is acted upon by some exterior force') since the essence of this law is to forbid the Galilean...
