Original sentence: In Motte's 1729 translation (from Newton's Latin), the second law of motion reads:.LAW II: The alteration of motion is ever proportional to the motive force impressed; and is made in the direction of the right line in which that force is impressed.— If a force generates a motion, a double force will generate double the motion, a triple force triple the motion, whether that force be impressed altogether and at once, or gradually and successively
Edited sentence: According to modern ideas of how Newton was using his terminology, this is understood, in modern terms, as an equivalent of:.If a force generates a motion, a double force will generate double the motion, a triple force triple the motion, whether that force be impressed altogether and at once, or gradually and successively.LAW II: The alteration of motion is ever proportional to the motive force impress'd; and is made in the direction of the right line in which that force is impress'd.Motte's 1729 translation of Newton's Latin continued with Newton's commentary on the second law of motion, reading:.Newton's Latin wording for the second law is:.The sense or senses in which Newton used his terminology, and how he understood the second law and intended it to be understood, have been extensively discussed by historians of science, along with the relations between Newton's formulation and modern formulations.This was translated quite closely in Motte's 1729 translation as:
