Introduction

Planisphere and didactic rotating platform for the study of Coriolis force and acceleration, which in physics is an apparent force observed in rotating non-inertial systems, which acts on bodies in motion with respect to the non-inertial reference system, and which has the apparent effect of deflecting bodies from a straight path.

Technical features

The rotating physical system is designed to mechanically reproduce a uniform rotary motion with a constant angular velocity value and to facilitate a first didactic demonstration of the effect of the Coriolis force. The Coriolis acceleration demonstrators present in the state of the art are equipped with expensive electrical systems and they present dangerous speed regimes and therefore not usable in the didactic field. Furthermore, there are no known didactic devices for studying the movement of aerial masses subjected to the Coriolis force. The purpose of the invention is to provide a rotating physical system capable of studying and displaying the action of the Coriolis force in the motions of bodies integral to a rotating system, which also allows to study and visualize the motion of aerial masses subject to the Coriolis force. The system consists of a flat circular element; a rotating device; a mechanical drag device designed to mechanically induce uniform rotary motion.
