What is another name for Newton's Second Law?

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

Answer: (D)

The main idea being tested is how a net force changes an object's motion. Newton's Second Law tells us that acceleration is produced by a net force and that its size depends on the object’s mass, summarized by F = ma. This is why it’s called the Law of Acceleration: it directly links the push or pull we apply to how quickly the object speeds up, slows down, or changes direction. For the same force, a heavier object accelerates less; for the same mass, increasing the force increases acceleration. The other options refer to different concepts—gravity to gravitational attraction, inertia to the tendency to resist motion changes, and Hooke's Law to springs—so the name that best captures the relation between force and motion is the Law of Acceleration.
