Rotation and effective gravity on Earth

How did you find PF?
Just heard of it a while back.
I'm interested in calculating effective gravity for a point-mass in a spinning gyro or swinging pendulum bob on a rotating planet undergoing any translational velocities and/or accelerations.

I want to investigate the theoretical effects of high-energy mechanical oscillation on orbital trajectory.

Still further I want to map out the underground pressures that have developed not only from true downward gravity but also as the force vector in the true horizontal plane (as distinguished from the ground plane) built up pressure while undergoing Coriolis effects. If such "rotational pressures" were released, how would the mantle move, where would be the centers of rotation, and along which lines would land areas slip past each other?

I want to know what happens if pressures in the Earth are released at disproportionate rates across the surface, specifically as during solar eclipse, or as land cools from day to night.

Finally, I would like to know how changing elastic pressures in the Earth might finally effect velocity of objects on the surface, and how the pressure would get transferred up. Could the low velocities of ground movent leverage into high velocity on small objects through a sort of elastic bounce?

Hello everyone, I was advised to join this community while seeking guidance on how to navigate the academic world as an independent researcher. My name is Omar, and I'm based in Groningen The Netherlands. My formal physics education ended after high school, but I have dedicated the last several years to developing a theoretical framework from first principles. My work focuses on a topological field theory (which I call Swirl-String Theory) that models particles as knotted vortex...
