Question:
If one could drill a hole through the center of the earth, from pole to pole. Jump down into the hole. Would the person eventually come to a rest in the center because of the forces of gravity?


Replies:
Yes, one would eventually come to rest at the center BUT because of the forces of friction (with the atmosphere in the hole). If there were no friction, you would just oscillate from pole to pole. The force of gravity at the center is actually ZERO because there is equal mass in all directions (equal gravitational pull in all directions).
