On http://www.gyroscopes.org/1974lecture.asp during segment 8 (from 2:18) an experiment with a gyroscope is conducted.(adsbygoogle = window.adsbygoogle || []).push({});

This is the clip of just that experiment

The gyroscope apparently has less mass. Where can I find math to describe this effect? What is this effect called formally?

Additionally, if this gyroscope were additionally orbiting in a circle with axis parallel to the gyro's axis of rotation, how would the effective centrifugal force of the gyro be calculated?
