Which scientist is credited with stating the three universal laws of motion?

• A. Isaac Newton
• B. Nicolas Copernicus
• C. Galileo Galilei
• D. Francis Bacon

Answer: (A)

The main idea is understanding who formalized the set of rules that describe how objects move when forces act on them. Isaac Newton is the scientist who stated the three universal laws of motion, establishing the foundation of classical mechanics in the 17th century. The first law describes inertia—an object remains at rest or moves uniformly unless an external force causes a change. The second law links force, mass, and acceleration with F = ma, showing how a net force changes an object's motion. The third law states that forces come in equal and opposite pairs, so every action has a corresponding reaction. Newton’s work in the Principia Mathematica (1687) crystallized these principles, whereas Copernicus proposed a heliocentric model, Galileo advanced studies of motion and experimental methods, and Francis Bacon helped formalize the scientific method but did not formulate these laws.
