What is the Hanging weight system that helps demonstrate the rotation of earth?

Answer 1

You're referring to the Foucault Pendulum.

If you can keep any pendulum swinging long enough without it dying out, you'll see that the 'plane'

of its swing rotates ... if you start it out swinging between the left and right walls of the room, then

it slowly turns to swing between the front and back walls, and eventually comes back around to the

left and right walls again. The time it takes to rotate depends on the latitude of your location.

The shortest possible period is 24 hours ... that happens with a pendulum at the north and south

poles. At the latitude of Glasgow or the tip of South America, it's about 29 hours; at the latitude of

Caracas Venezuela or Lima Peru, it's over 130 hours; at the equator, it doesn't rotate at all.

Answer 2

The hanging weight system is a simple pendulum apparatus used to demonstrate the rotation of Earth. By observing how the pendulum's plane of oscillation appears to rotate over time, one can visualize the Coriolis effect caused by Earth's rotation. This system helps to illustrate how the rotation of Earth influences the movement of objects in the atmosphere, such as wind patterns.
