cheque and theface of a pendulum is observed in a rotating reference frame the
pendulum is filled with Inc there's a small
opening at its bottom the the chair is set
into motion then the pendulum is released it for the
observer at rest the swinging pendulum moves along a fixed pass for the accelerated observer
however it moves on resent like rotating part yeah In
repeating the experiment the pendulum is
kicked out of its equilibrium position again a time-varying pass in the form of a rosette is observed although 1 with a different form and as long as

Abstract The demonstration of inertial forces in accelerated frames of reference. These forces do not occur in reference frames which are not accelerated (inertial frames). Rotating frames of reference are also accelerated even when the angular velocity is constant. In such a frame, the Coriolis force acts on moving objects in a direction perpendicular to their motion. For freely moving objects, this leads to a curved path. Such paths, in the form of rosettes, will be shown for a simple pendulum swinging on a rotating chair. This experiment is in principle identical to that of the Foucault pendulum, with the earth being the rotating reference frame, the only difference being that the earth rotates about ten thousand times more slowly than the rotating chair in the lecture hall.
