a related thought experiment to a tunnel through Earth through which a person falls to the other side, is what if it was a pendulum falling through the planet?
first, a pendulum is at 90 degs to the G field; 2nd, as soon as the pendulum BEGINS to fall through, it is in free fall, and it will continue its last swing in the same direction, at the same speed as it had when it began to fall, describing a circle. the pendulum's ACCELERATION will decrease until reaching the center of the Earth whereupon it will begin DECELLERATING until reaching the other side of the earth, all the while continuing describing the same circle. IF then, it is stopped, it will once again begin operating as a pendulum.
