What does Newton's second law of motion primarily relate to?

• A. The relationship between mass and velocity
• B. The relationship between force and acceleration
• C. The relationship between energy and motion
• D. The relationship between mass and energy

Answer: (B)

Newton's second law of motion primarily relates to the relationship between force and acceleration. This law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. In mathematical terms, it is commonly represented as F = ma, where F is the net force, m is the mass, and a is the acceleration. This principle underlines how the application of force will change an object's motion, with greater force resulting in greater acceleration, provided the mass remains constant. Understanding this relationship is fundamental in studying dynamics and the effects of forces on objects in motion.
