How does a pendulum not stop?

If there were no friction or drag (air resistance), a pendulum would keep on moving forever. In reality, each swing sees friction and drag steal a bit more energy from the pendulum and it gradually comes to a halt. But even as it slows down, it keeps time.

Does a pendulum ever stop in 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. Why a pendulum does not oscillate in zero gravity? The string will not have any tension in it since the bob is not exerting a force on it (by moving away). Therefore, a pendulum cannot oscillate in space (absence of a gravitational force.) There is gravitational force in space!

Also, what is the pendulum theory?

Also called pendulum law . a law, discovered by Galileo in 1602, that describes the regular, swinging motion of a pendulum by the action of gravity and acquired momentum. the theory holding that trends in culture, politics, etc., tend to swing back and forth between opposite extremes. Would the pendulum oscillate longer or shorter on the moon? The force of gravity is less on the moon than on the Earth. Since the force of gravity is less on the Moon, the pendulum would swing slower at the same length and angle and its frequency would be less.

Regarding this, can pendulums find things?

Find What You're Looking For... Using a Pendulu. (Now, it doesn't have to be a crystal pendulum...it can be any pendulous object at all in fact). Pendulums & other dowsing objects, like dowsing rods (L rods or Y rods), have been used throughout history to locate objects or resources. What is the best material for a pendulum? The best material is quartz because of its proven stability and low thermal expansion. Steel is used for the pendulum rod in simple ordinary clocks because it is cheap and has relatively low thermal expansion.
