Newton's Second Law

Newton's second law of motion states that an object accelerates because a force acts on it. The stronger the force, the greater the acceleration. Newton defined the mass of an object as the link between the force on the object and the object's acceleration. Newton's relation is shown by the equation: force = mass x acceleration.
