...with scientific laws of nature: Newton's first law of motion, "Every body continues in its state of rest, or of uniform motion in a right line, unless...to change that state by forces impressed upon it", is not a law applicable only to particular bodies, or bodies considered from a certain point of view;...

It is stated as follows: AXIOM I: Every body continues in its state of rest, or of uniform motion in a right line, unless...to change that state by forces impressed upon it. The content of this axiom is contained in the third definition that precedes the axiom. It reads as...

...Newton took Galileo's discovery to be founded on two laws: (i) that every body continues in its state of rest, or of uniform motion in a right line, unless...to change that state by forces impressed upon it; (ii) that the change of motion is proportional to the motive force impressed; and is nude in the direction...

...is generally stated, "Every body continues in its state of rest, or of uniform motion in a straight line, unless it is compelled to change that state by forces impressed upon it." 52 The difference in Newton's statement is that he begins with a "state of rest" as a default before...
