"The second law of motion is: 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. And this motion (being always directed the same way with the generating force), if the body moved before, is added to or subtracted from the former motion, according as they directly conspire with or are directly contrary to each other; or obliquely joined, when they are oblique, so as to produce a new motion compounded from the determination of both."

The second law of motion states that Force = mass * acceleration, or in other words, that force is directly proportional to acceleration.
The first law follows because it states that an object at rest or in uniform motion will stay that way unless a force acts upon it. Being at rest or in uniform motion means acceleration is zero. Anything times zero is zero, so no acceleration means no force, and vice-versa.

II. The relationship between an object's mass m, its acceleration a, and the applied force F is F = ma. Acceleration and force are vectors (as indicated by their symbols being displayed in slant bold font); in this law the direction of the force vector is the same as the direction of the acceleration vector.
