Newton's Second Law is commonly named what?

• A. The Law of Acceleration
• B. The Law of Inertia
• C. Hooke's Law
• D. The Law of Gravity

Answer: (A)

Newton's Second Law describes how a net force makes an object accelerate, and how that acceleration depends on the force and the object's mass. Because it directly links force to the change in motion, it’s commonly called the Law of Acceleration. The relation F = ma shows that acceleration grows with force and shrinks with mass, so doubling the force (with the same mass) doubles the acceleration, while doubling the mass (with the same force) halves the acceleration. If no net force acts, the acceleration is zero, meaning the motion stays constant. It’s not about inertia, which is the tendency of an object to resist changes in its motion (that’s Newton’s First Law). It’s not Hooke’s Law, which describes springs where force is proportional to displacement. It’s not the Law of Gravity, which describes the attraction between masses.
