...fit, iiihil fit a 2 Newton's Three Laws of Motion, " Principia," Introduction, are as follow : 1st. Every body perseveres in its state of rest, or of...in a right line, unless it is compelled to change its state by forces impressed upon it. 2d. Change of motion is proportional to the motive force impressed,...

The principle of persistence grows out of a consideration of Newton's first law of motion : " Every body perseveres in its state of rest, or of...compelled to change that state by forces impressed thereon." This is, of course, only the principle of inertia, which is simply another, and it has always...

...by Sir Isaac Newton. He called it the First Law of Motion and put it into these words : — " That every body perseveres in its state of rest or of uniform motion in a right line except in so far as it is compelled by forces to change that state." § 8 1. INERTIA — FORCE. —...

Every body perseveres in its state of rest or of \iniform motion in a right line, unless it is compelled to change that state by forces impressed thereon. 2. The alteration of motion is ever proportional to the motive power impressed, and is made...
