The pendulum clock inventor mentioned in the material is which scientist?

• A. Hygens
• B. Robert Hooke
• C. Galileo
• D. Aristotle

Answer: (A)

The main idea here is recognizing who first linked a swinging pendulum to regulating a clock. Christiaan Huygens is the scientist associated with inventing the pendulum-regulated clock. He built the first practical pendulum clock in the mid-1600s and showed that a pendulum’s regular swing could keep time, especially for small amplitudes. His work on the clock mechanism, including the introduction of the anchor escapement, reduced friction and allowed a longer pendulum, which dramatically improved accuracy. This combination—the pendulum’s steady period and a reliable escapement—made the pendulum clock feasible and significantly more precise than earlier timekeepers. While Galileo explored pendulum motion and isochronism and Hooke contributed to clock ideas, the credited inventor of the pendulum clock in the material is Huygens. Aristotle, much earlier, isn’t associated with pendulum clocks.
