Which one is Newton's second law of motion? The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object. The acceleration of an object as produced by a net force is inversely proportional to the magnitude of the net force, in the same direction as the net force, and directly proportional to the mass of the object. $F=\frac {m}{a}(\frac {m}{s^{2}})$ $F=\frac {a}{m}(N)$
