Equation of the Week [June 24, 2013]

Newton's laws of motion are three physical laws that laid the basis for classical mechanics:

1. An object remains in uniform velocity, or rest if it is in rest, with respect to an inertial reference frame, unless acted on by an outside force. Mathematically .

2. The acceleration of a body is directly proportional to, and in the same direction as, the net force acting on the body, and inversely proportional to its mass. Mathematically .

3. Every force exerted on a body is simultaneously being exerted on a force equal in magnitude and opposite in direction. Mathematically .
