The Foucault pendulum or Foucault's pendulum is a simple device named after French physicist Léon Foucault, conceived as an experiment to demonstrate the Earth's rotation. If a long and heavy pendulum suspended from the high roof above a circular area is monitored over an extended period of time, its plane of oscillation appears to change ...
The oldest Foucault Pendulum in Romania is located in pavilion B of the University of Oradea. It was installed in 1964 by Prof. Coriolan Rus, the then dean of the Faculty of Mathematics - Physics. (length: 14m; weight: 60 kg) "Vasile Alecsandri" National College in Galați (length: 9,92m; weight: 8 kg)
The Foucault pendulum connection is constructed such that the pendulum is free to swing in any direction. This is not the same thing as the support connection being free to rotate (spin). The swing of the pendulum is different from the rotation (spin) of the bob.
An additional example of a nonholonomic system is the Foucault pendulum. In the local coordinate frame the pendulum is swinging in a vertical plane with a particular orientation with respect to geographic north at the outset of the path. The implicit trajectory of the system is the line of latitude on the Earth where the pendulum is located.

If one rotates [a heavy shell of matter] relative to the fixed stars about an axis going through its center, a Coriolis force arises in the interior of the shell; that is, the plane of a Foucault pendulum is dragged around (with a practically unmeasurably small angular velocity).
"Simple gravity pendulum" model assumes no friction or air resistance. A pendulum is a device made of a weight suspended from a pivot so that it can swing freely. [1] When a pendulum is displaced sideways from its resting, equilibrium position, it is subject to a restoring force due to gravity that will accelerate it back toward the equilibrium position.
Original - Animation of a Foucault pendulum showing the sense of rotation on the southern hemisphere. The rate of rotation is greatly exaggerated. A real Foucault pendulum likes to go weeeeeeeeeeeeeeeeeeeeeeeee and swing back and forth, released from rest, does not pass directly over its equilibrium position as the one in the animation does.
