If a hole was drilled through the earth and I fell down it when would I stop falling and start climbing??

Question

there is no bottom of the hole abus I mean right the way through earth to the other side

Answer 1

Of course part of the center of the earth is molten lava and you can't drill such a hole. But it is an interesting question as to how gravity would work in a theoretical hole. As you stand by the hole you have maximum potential energy (elevation) and zero kinetic energy (velocity). After jumping into the hole you gain speed (kinetic energy) as you lose elevation (with respect to the center of the earth). Potential energy is converted exactly to kinetic energy with no net gain or loss in total energy. At the center you have maximum velocity but zero elevation and speed on through to the other side losing speed but gaining elevation. Neglecting air friction and friction from hitting the sides of the hole, you would exactly land on your feet on the other side and could make a return trip oscillating back and forth (like a swing) forever (in an ideal frictionless world).

Answer 2

Assuming you fall feet first then surely you will fall out the bottom. Unless you wedge your knees against the sides and start climbing back the way you came, like a Chimney Sweep...

Answer 3

Suppose you dont melt down with the heat,

You will stop falling near the core.
Then you can come out of the other way with a little extra force applied. It will be somehow like climbing a hill.

Answer 4

You would stop falling around the core, and remain stationary there, because of opposing gravitational forces from all sides. At that point, you would have already been dead for some time, as no human can survive the temperatures of the mantle and core.

Answer 5

hypothetically speaking, if you could survive

you would remain stationary, but you would be able to climb out of it, your force vs gravity. The gravity from all directions wouldnt hold you still, it would just put extra weight on you from all directions, you could pick a side, as you rotate

Answer 6

I think you would fall downward for about a block, thereafter you would begin to automatically rise back to the surface carried by the air in your head.

Answer 7

when you hit the bottom of the hole. are you blonde by chance.

Answer 8

Well, I think you would melt long before the way up.

Answer 9

i dont think you would know on account of you would already have incinerated
