The Second Law of Motion, formulated by Isaac Newton, states that the acceleration of an object depends on the net force acting upon it and its mass. This relationship is expressed by the formula F = ma , where F is the net force, m is the mass, and a is the acceleration. Essentially, the greater the force applied to an object, the greater its acceleration will be, provided the mass remains constant. This law also implies that heavier objects require more force to achieve the same acceleration as lighter ones. For example, pushing a car requires significantly more force than pushing a bicycle to reach the same speed. Understanding this principle helps explain how objects move and interact in our physical world.
