In the third law, when two objects interact, they apply forces to each other of equal magnitude and opposite direction. This means that if a force is applied to an object, it will accelerate in the direction of the force, and the acceleration will be greater the greater the force and the smaller the mass of the object. Newtons First Law of Motion (Inertia) An object at rest remains at rest, and an object in motion remains in motion at constant speed and in a straight line unless acted on by an unbalanced force. Newtons Second Law of Motion says that acceleration (gaining speed) happens when a force acts on a mass (object). Now, one can argue that Newton's Second Law of Motion leads to the First Law.
