Final answer:
Newton's second law of motion confirms that force is related to the mass and acceleration of an object, meaning that the law indeed deals with how force affects motion.
Step-by-step explanation:
True, Newton's second law of motion deals with the relationship between force, mass, and acceleration. The law states that the acceleration of an object is directly proportional to the net external force acting on it and inversely proportional to its mass. In other words, the more force that is applied to an object, the more it will accelerate, and the greater the mass of the object, the less it will accelerate when the same force is applied. This relationship is fundamental in physics as it helps us predict how objects will move when subjected to various forces, making it a cornerstone of mechanics and motion studies.
