By the way, there is no such things as
"1) perpendicular to the center of the earth
2) perpendicular to the sum of forces (ie. rotational energy and gravitational energy"

Cener of earth is a POINT. How can something be perpendicular to a point?

Also, rotational and gravitational ENERGY are NOT FORCES. Energy is SCALAR, it does NOT have a direction.

Also, there is no rotational force (there is centripetal force directed to the center).

Also, PERPENDICULAR to sum of g ang w^2r is actually HORIZONTAL, not VERTICAL.

Did you ever study any physics by chance?
