Dynamic Gravity Experiment with Physical Pendulum

In recent decades, several methods significantly different from the classic method of the Cavendish torsion balance have been developed and used for measuring the gravitational constant G. Unfortunately, the new de-terminations of G have not reduced significantly its uncertainty. It seems that in recent times, the accuracy prob-lem for the gravitational constant has not been the focus. This paper presents a new type gravity experiment used a big and heavy physical pendulum, not for a newest gravitational constant measure, but for the study of special gravitational effects encountered accidentally. Surprisingly strong gravitational effects have been observed between moving masses. We have named the whole new group of gravitational phenomena by dynamic gravity. Despite the simplicity of our gravity experiment, the observed extraordinary results could lead to an unexpected revolution in gravity science.
