(...) I've wondered this in the past also. If the planet were not rotating, I think the answer would be that your analysis is correct. Note that you would be in a zero-G environment (or close to it) at the center assuming the Earth is close to an (...) (22 years ago, 2-Oct-02, to lugnet.off-topic.debate)

(...) Never thought about the rotation--there was an H.G. Wells story about a guy that was granted a wish and his was for the earth to stop spinning--turns out that when the wish was mentioned, the earth stopped instantly anad everything that wasn't (...)

(...) Ok, that would eliminate the rotation. (...) Since your original problem statement assumed there was no problem with a molten core, I think it's also reasonable to assume the water isn't a problem (you can make a dam from all the earth you (...)

(...) Would it be a $#*crash*#$ into the side or more of a 'rubbing' every once in a while to stop the sideways velocity. Considering that gravity is pulling straight down, and the original velocity from the surface spin is moving you east at (...) (22 years ago, 3-Oct-02, to lugnet.off-topic.debate)

Quoting David Koudys <dkoudys@redeemer.on.ca>: (...) I think it'll feel like you're rolling down a steep hill, constantly crashing against the eastern wall. (...) uh, why? gravity is pulling straight down, your momentum is at 90 degs to the force - (...) (22 years ago, 3-Oct-02, to lugnet.off-topic.debate)

Now that I pictured that, I understand it better--the force of gravity is always pointing straight to the center from the object, even if you're a foot to the right from where you were a second ago--my visual image is reprocessed--thanks!

(...) Which of course happens as soon as you pass the center... Though the friction of rolling down the side of the tunnel might be enough to stop you at the center. Frank (22 years ago, 3-Oct-02, to lugnet.off-topic.debate)

(...) The terminal velocity will primarily be a function of the density of the air and the surface area of the body. The force being applied will have some effect. Basically what will happen is that near the center of the Earth, the friction from (...) (22 years ago, 3-Oct-02, to lugnet.off-topic.debate)
