At any point of time, at any specific point on the surface of this earth, gravity can be properly represented as a single vector, with one stated value, and one specified direction! At this specific point of time and position and direction, a plane can be positioned so that there is no component or part of the gravity vector lying in the plane. That is, the plane is exactly perpendicular to the direction of the gravity at that point and time. Now at this same point, other than at one of the two poles of this earth, there will normally be a centrifugal force vector. And this centrifugal force will normally not be perpendicular to this plane. Only at or near the equator would such conditions be expected. And thus, in these planes that are perpendicular to the gravity, there will normally be a component of the centrifugal force in these planes.
