...scientific age than any of his contemporaries' work. They may be stated in the following form: (i) Every body continues in its state of rest or of uniform motion in a straight line except insofar as it is compelled to change that state by an external impressed force, (ii) The rate of change...

...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 a definition of...

...force can be stated in the form of a law as follows: "Every body perseveres in its state of rest or of uniform motion in a straight line except in so far as H is compelled to change that state by impressed forces." This is called Newton's first law of motion....
