Newton's Second Law states that the acceleration of an object depends on the net force acting on it and its mass. This relationship is often expressed with 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 more it will accelerate, while a heavier object will require more force to achieve the same acceleration as a lighter one.
This law helps explain everyday phenomena, such as why a car accelerates faster than a truck when the same force is applied. It also underpins many principles in physics and engineering, guiding the design of vehicles, machinery, and various technologies by predicting how they will respond to different forces.
