Frequency Dependence of Rotor's Free Falling Acceleration and Inequality of Inertial and Gravity Masses

TL;DR

This study investigates how the rotation frequency of a gyroscopic rotor affects the free fall acceleration of a container, revealing potential violations of the equivalence principle and suggesting high-resolution ballistic gravimetry methods.

Contribution

It provides experimental data showing frequency-dependent variations in free fall acceleration, challenging the assumption of inertial and gravitational mass equivalence.

Findings

Negative acceleration changes dominate at 20-400 Hz

Resonant maxima and minima observed at specific frequencies

Data suggest possible violation of equivalence principle

Abstract

Results of measurements of free falling acceleration of a closed container with a rotor of a mechanical gyroscope placed inside it on the frequency of the rotor rotation are briefly described. Time of separate accelerations measurements is 40 ms, the period of sampling is from 0.5 up to 1.0 minute. In rotation's frequencies range of 20-400 Hz, the negative changes of free falling container acceleration prevail. On individual frequencies the "resonant" maxima and minima of acceleration are observed. The obtained data apparently contradict the equivalence principle of inertial and gravitating masses. The expediency of development of ballistic gravimetry of high time resolution with use of rotating or oscillating test bodies is noted.
