Science Lab Centrifugal Force Apparatus

Specification:

The device is composed of a track where a low friction bobbin can run.  
By rotating the device with the rotation device, it is possible to read the value of the centrifugal force on the Newton spring scale fixed about the rotation axis.  
Measuring the frequency of rotation is required and can be achieved using any of our light gates.
Moreover, it is possible to verify the centrifugal force formula too, knowing the radius
