Step 1
As you fall, the mass of the Earth "above" you pulls you upwards, while the mass "below" you pulls you downwards. The net effect is that the gravitational force decreases linearly as you approach the center. Show more…

Pretend you fall into a hole bored completely through the Earth. Discounting friction and rotational effects, rank from greatest to least positions A, B, C, and D for your a. speed. b. acceleration toward Earth’s center.
Pretend someone actually managed to dig a hole straight through the center of the Earth all the way to the other side. If an object were dropped down that hole, which of the following would best describe its motion? Assume ideal conditions and that the object cannot be destroyed. (A) It would fall to the center of the Earth and stop there. (B) It would fall through the hole to the other side, continue past the opposite side’s opening, and fly into space. (C) It would oscillate back and forth from one opening to the other indefinitely. (D) It would fall to the other side and stop there.
