The relationship between force and motion is dictated by Newton's laws of motion. Specifically, Newton's second law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. Essentially, a greater force applied to an object results in greater acceleration, leading to changes in motion. Force can alter the speed or direction of an object's movement. Understanding this relationship is fundamental in physics, as it helps explain both static and dynamic systems and underpins engineering, mechanics, and various fields of science.
