If we standing in the equator, then centrifugal force caused by Earth rotation directly balanced by gravity force. But what if we standing in the high altitude or in the pole? In the pole at the distance like 40 km from north pole (so the north pole inside the horizon plane), the gravity have no component parallel to the ground, because gravity perpendicular to the ground, so we don't have experienced force by gravity to the left, right, back, or front. But the Earth rotation makes us experienced centrifugal force that have component (projection) parallel to the ground. So at this distance we must travel with linear speed like 2 m/s. But why we never experienced this centrifugal force at the pole?
