Let's set a reference point very far away from the Earth which holds unmoved.

If I am at the equator and the Earth starts to accelerate to the escaping speed on the surface, my guess is I will be shaken off the Earth. My relative speed to the materials that make the Earth is zero near me and big to the materials on the other side of the Earth thus a net relative speed.

If I am at the north pole and the earth rotates faster then I should stay feeling the same gravitational force. My relative speed to the materials of Earth is zero cause they cancel each other at different locations.

If I speed up and shoot off the earth, my relative speed to the earth is big as Newton has told us.

Now what happens if I jump up into the air and the Earth starts rotating faster and faster? My guess is I will fall back to the ground and hit hard. Again my relative speed to the materials that made Earth is zero in this case because they cancel each other again.

My question is, does the effective force I feel from the materials that make Earth has any correlation with their relative speed to me or not? More particularly, relative angular momentum and gravity.
