Newton's second law of motion can be formally stated as follows:

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.

This verbal statement can be expressed in equation form as follows:

The above equation is often rearranged to a more familiar form as shown below. The net force is equated to the product of the mass times the acceleration.
