FAQs on Pendulum Clock Video Lecture - Science (Curiosity) Class 7 - New NCERT

1. What is a pendulum clock and how does it work?

Ans. A pendulum clock is a timekeeping device that uses a swinging pendulum to regulate the passage of time. The pendulum swings back and forth at a constant rate, and this motion is used to measure time intervals. The clock mechanism includes gears that translate the pendulum's motion into the movement of the clock hands, allowing it to keep accurate time.

2. Why is the pendulum important in a pendulum clock?

Ans. The pendulum is crucial because it provides the regular motion needed for accurate timekeeping. Its steady swing creates a consistent time interval, which the clock's gears use to measure seconds, minutes, and hours. The length of the pendulum also affects the speed of the swing, thereby influencing how fast or slow the clock runs.

3. Who invented the pendulum clock and when?

Ans. The pendulum clock was invented by Dutch scientist Christiaan Huygens in 1656. His invention significantly improved the accuracy of timekeeping, allowing clocks to achieve precision within seconds over the course of a day.

4. What factors can affect the accuracy of a pendulum clock?

Ans. Several factors can affect the accuracy of a pendulum clock, including temperature changes, which can alter the length of the pendulum, and air resistance, which can slow down the pendulum's swing. Additionally, the clock's mechanism must be properly maintained to ensure it operates smoothly.

5. How do you maintain a pendulum clock for accurate timekeeping?

Ans. To maintain a pendulum clock, ensure it is placed on a level surface to prevent irregular swinging. Regularly check and adjust the pendulum length for accuracy, and clean the clock mechanism to avoid dust build-up. It's also important to wind the clock as required and replace any worn-out parts to keep it running smoothly.
