Newton`s Second Law.
... 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. This is of course, the famous “F = ma”, once we interpret “alteration of motion” as “acceleration” and combine “motive force” and “direction o ...
