Newton's Second Law Formula – Force = Mass × Acceleration

Newton's Second Law of Motion is one of the most important equations in all of physics. It states that the net force acting on an object equals its mass multiplied by its acceleration: F = ma. This simple formula underpins everything from rocket propulsion to car safety design and explains why heavier objects are harder to accelerate.
