Electrical rotating platform

Optika rotating platform allows students not only to verify the relations between the fundamental quantities which characterize rotational motion, but also to perform experiments on an important topic: inertial and non-inertial systems. What is seen by an observer on an inertial system is different from what is seen by an observer on a non-inertial system.
In this way students are allowed to understand which is the origin and which are the results of fictitious forces as the centrifugal force and Coriolis force.
Thanks to this platform, you are able to study a lot of fundamental topics as the effects of Coriolis force on solids and liquids and understand why a athematical instrument as the cross product was so important. By which magnitudes the centrifugal force depends on? Let’s perform some experiences with OPTIKA rotating platform.
