if you dug a hole thrugh the earth?

Question

(you know pretend like it could happen)

you dig it then jump in it
you fall all the way to the other side of the earth
when you get to the other side of the earth
would just fall back to the spot you started?
and so on...

i was thinkin about this today

Answer 1

you wouldnt get to the other side.

You're constantly being attracted towards the Earths centre of mass. Gravity. You'd be pulled towards the centre and accelerate to a ridiculous speed as you got close.

Thinking about it like that, you would overshoot the mark due to your speed and then be drawn back towards the centre, overshoot, and that process would repeat several times until you come to rest in the dead centre.

By the way, I'm assuming for simplicity that we're just imagining the Earth as being solid rock and not having a molten core.

Answer 2

In a purely theoretical situation (no heat to burn you up, the center of the Earth being the center of gravity, etc), you would fall almost to the far side, then reverse direction and fall almost to the place you started, and a little less and lesseach time--similar to a rubber ball bouncing lower and lower as it goes-- until you finally stopped at the center.

BUT, I think there's a technical twist to this. Let's say you are half way to the center of the Earth--about 1000 miles. You now have x amount of mass pulling you toward's the center. But you also have the mass above you pulling you in that direction. I would love to hear from a university professor or a NASA engineer or some such person to hear their views on how that reverse pull would affect an object that was, say, 1500 miles from the surface of the Earth. What percentage of original pull is still being applied in the "down" direction?

But, I guess that's another question for this forum.

Answer 3

Hypothetically speaking, particular. yet in ordinary terms after countless rocking around the centre. you may shoot previous the centre due on your momentum from the fall, and attain in simple terms approximately the comparable height you have been at formerly falling in, yet then gravity might take over and you may fall circulate into opposite returned. After each and every fall, you may lose some momentum, till you're caught on the centre of the planet.

Answer 4

You would almost get to the other side and you would fall back to where you started but you wouldn't be high enough to grab on and get out and you would go back and forth until you would get stuck in the middle.

Answer 5

the earth is attracting any object towards its center so in ideal situations you will continue the journey from center to surface to center to other surface to center and so on ...this is called simple harmonic motion.....how ever practically for every trip you will lose some of your velocity overcoming friction and eventually stop at center......what say.....wanna jump??

Answer 6

You are right. You will do Simple Harmonic Motion around the centre of the Earth.

Answer 7

if you dug a hole you would be lucky to get past the core of the earth, as its full of hot magna, so you would only get half way

Answer 8

you would fall to the center of the earth where gravity would be equal on all sides

Answer 9

You would burn up and die due to the intense heat or get crushed by the immense pressure... : /

Answer 10

Well, right after your shoes melted your shovel would melt...
