How do you maintain a pendulum clock?

Lengthening the pendulum slows down the clock; shortening it makes the clock run faster. Remember to always turn the hands clockwise, never counterclockwise, to set the time, so as not to bend or break strike-mechanism levers.

One may also ask does a foucault pendulum stop?

To keep the Foucault Pendulum going, one must replace the energy lost with each swing. This restores the energy lost during the swing and keeps the pendulum from stopping. It has no effect on the direction of the swing, and thus does not interfere with the demonstration that the earth is rotating. Correspondingly, who invented the pendulum? Christiaan Huygens Pendulum clock / Inventor. Such was the case with 17th century Dutch astronomer Christiaan Huygens. He became the first to report the phenomenon of coupled oscillation in two pendulum clocks (which he invented) in his bedroom while recovering from an illness in 1665.

Then, how does earth's rotation affect a pendulum?

And each time the pendulum swings; the Earth rotates a little more. You start the pendulum swinging in a perfect east-west direction. The Earth still rotates each time the weight goes through an arc, but now it's moving in exactly the same direction as the pendulum. Will a pendulum stop in a vacuum? In a vacuum with zero air resistance, such a pendulum will continue to oscillate indefinitely with a constant amplitude. However, the amplitude of a simple pendulum oscillating in air continuously decreases as its mechanical energy is gradually lost due to air resistance.

Can a pendulum oscillate in space?

Therefore, a pendulum cannot oscillate in space (absence of a gravitational force.) Why does a pendulum stop in a vacuum? The pendulum has a fixed amount of energy. All that is happening is the energy getting converted from potential energy to kinetic energy during the oscillation of the pendulum. Once you start extracting energy, the pendulum slows down, and ultimately stops.
