Which of the following statements is true about Newton's laws of motion?

Newton's laws of motion are fundamental principles that describe the relationship between the motion of an object and the forces acting on it. The second law, in particular, directly illustrates this relationship by stating that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. This means that the laws are applicable regardless of whether an object is stationary or in motion, and they can be used to analyze the behavior of both small and large masses, as well as objects in various environments, including those with resistance such as air or friction. Thus, the statement that they involve the relationship between motion and forces correctly captures the essence of Newton's laws.
