1/10 Questions

The gridiron pendulum clock was invented by...
- Isaac Newton
- Jones Harrison
- George Graham
- Christian Holmes

About This Quiz

Using either a pendulum or a swinging weight for timekeeping, a pendulum clock is a harmonic oscillator which swings forward and backward in an exact time interim subject to its length and opposes swinging at different rates.

2.

A major source of errors in pendulum clocks is...
- Thermal expansion
- Mechanical expansion
- Mechanical relativity
- Thermal relativity
Correct Answer

A. Thermal expansion

Explanation

Thermal expansion is a major source of errors in pendulum clocks. As the temperature changes, the metal components of the clock expand or contract, causing variations in the length of the pendulum. This change in length affects the period of the pendulum's swing, leading to inaccuracies in timekeeping. Therefore, thermal expansion can cause the clock to run either faster or slower than it should.

The Pendulum Clock was invented by...
- Isaac Newton
- Michael Faraday
- Galileo
- Christian Huygens
Correct Answer

A. Christian Huygens

Explanation

Christian Huygens is the correct answer because he is credited with inventing the pendulum clock. Huygens, a Dutch scientist, developed the concept of using a pendulum as a regulator for timekeeping in the mid-17th century. He designed and built the first practical pendulum clock, which greatly improved the accuracy and precision of timekeeping devices. Huygens' invention revolutionized the field of horology and his pendulum clock became the standard for accurate timekeeping for centuries to come.

The Mercury pendulum clock was invented by...
- Isaac Newton
- Galileo
- George Graham
- Jones Smith
Correct Answer

A. George Graham

Explanation

George Graham is the correct answer because he was the inventor of the Mercury pendulum clock. This type of clock, also known as a mercury regulator, was a significant improvement in timekeeping accuracy compared to previous pendulum clocks. Graham's design incorporated the use of a jar filled with mercury, which acted as the pendulum's weight and also compensated for changes in temperature. This innovation greatly improved the clock's precision and made it a popular choice for accurate timekeeping during the 18th century.

5.

The pendulum clock uses pendulum as its...
- Movement elements
- Time storing swing
- Swing element
- Time keeping element
Correct Answer

A. Time keeping element

Explanation

The pendulum clock uses a pendulum as its time keeping element. The pendulum swings back and forth at a constant rate, which regulates the movement of the clock's gears and hands. The length of the pendulum determines the speed at which the clock runs, with longer pendulums resulting in slower timekeeping. By counting the swings of the pendulum, the clock can accurately measure the passage of time.

The Mercury pendulum clock was invented in...
- 1720
- 1721
- 1734
- 1742
Correct Answer

A. 1721

Explanation

The correct answer is 1721. The Mercury pendulum clock was invented in 1721.

7.

Which year was the Pendulum Clock invented?
- 1655
- 1656
- 1670
- 1657
Correct Answer

A. 1656

Explanation

The correct answer is 1656. The pendulum clock was invented by Dutch scientist and inventor Christiaan Huygens in 1656. This invention marked a significant advancement in timekeeping technology, as it provided a more accurate and reliable way of measuring time compared to previous mechanical clocks. The pendulum clock became widely used and remained the most accurate timekeeping device for nearly 300 years until the invention of quartz clocks in the 20th century.

The gridiron pendulum was invented in...
- 1726
- 1734
- 1742
- 1725
Correct Answer

A. 1726

Explanation

The gridiron pendulum was invented in 1726.

9.

Which of the following is not a Pendulum Clock?
- Lantern
- Banjo
- Bird nest
- Cuckoo
Correct Answer

A. Bird nest

Explanation

A pendulum clock is a type of clock that uses a swinging pendulum to regulate its timekeeping. The lantern, banjo, and cuckoo are all types of clocks that can have pendulums. However, a bird nest is not a clock and therefore cannot be a pendulum clock.

10.

The movement of all mechanical pendulum clocks have how many parts?
- 1
- 5
- 3
- 6
Correct Answer

A. 5

Explanation

A mechanical pendulum clock consists of several essential parts that enable its movement. These parts include the pendulum, which swings back and forth to regulate the clock's timekeeping, the escapement mechanism, which controls the release of energy to the pendulum, the gear train, which transfers the energy from the escapement to the clock's hands, the hands themselves, which indicate the time, and the clock movement, which houses all these components. Therefore, a mechanical pendulum clock typically has five parts involved in its movement.
