if u could, what would happen if u drilled a hole through the earth and jumped in to it.?

Answer 1

This is an interesting question if we assume that the earth were solid all the way through and not hot at the centre and that the hole filled with air that you could breathe and nothing else killed you. Then you would fall with increasing speed until you passed the centre of the earth when you would slow down as gravity began to pull you back. Eventually you would stop when you got to the surface the other side (or close to it) and begin to fall back again. This would happen repeatedly. Gradually the air resistance would reduce the height that you came up to each time until finally you stopped at the centre of the earth. (I think that's what would happen.)
Wait a minute. If someone falls from an aircraft without a parachute they fall faster and faster but not over about 150mph when the air resistance counteracts gravity. This would happen in the hole so you might not go too far past the centre before falling back. Delete the words "surface the other side or close to it" from the above. By the way, I hope that you are asking this question out of general interest and not because it is your homework. In that case delete all of the above!

Answer 2

If you drilled down to the mantle (depending of course where on the earth's surface you were) you would release pressure and there would be an up welling of magma. So you cannot drill a hole through the earth with present technology let alone jump in it. So grow up!

If you are feeling suicidal there are other means of testing Earth's gravity.

Answer 3

The question will be answered if we make proper the following assumptions: (a million) The earth isn't spinning. (2) The earth is of uniform density for the time of. (3) the hollow varieties a diameter of the earth (i.e., it passes by the earth's center). the hollow must be by the middle; in the different case, the gravity from the earth would pull you into the area of the hollow ultimately; your action would not exist alongside a immediately line for an similar reason that a bullet shot immediately ahead falls in the route of the floor. (4) there is not any air resistance. The gravitational rigidity vector will continually think about the route of the middle of the earth alongside the route of the hollow no count number what route you're transferring in and its importance will be proportional for your distance from the earth's center. In symbols, the rigidity will be of the type ok(c - v), the position v is your position vector and c is the area vector of the earth's center. this can reason you to execute harmonic action--you'll oscillate decrease backward and forward. you would attain the different end of the hollow at which factor you would quickly provide up and then commence falling interior the different route. you would proceed to pass decrease backward and forward between the ends of the hollow conserving a consistent finished mechanical power.

Answer 4

You would fall down, past the centre, and then oscillate, until you eventually came to a rest near the centre of the earth.

BUT you would not be hovering, this could only be done in theory.

You would be attracted to a side of the hole, and end up stuck there near the centre.

If you imagine magnets arranged in a circle close to, but not touching, a steel ball. It would be impossible to make the ball stay in the middle of the space surrounded by magnets. The ball would end up sticking on one of the magnets, even though in theory the ball would experience a zero net force when it was in the centre of the ring of magnets.

Answer 5

You would accelerate towards the center of the Earth starting at 1 G (9.8 m/s^2). That acceleration would change as you approach the center to 0. The velocity you would attain would send you towards the other side of the planet but air friction would slow you down to the point where you would not reach it. You would bounce back and fourth until air friction slowed you down to a point where you would come to rest at the center of the Earths core. Assuming you didn't already burn up, or die from lack of water, food, etc.

From a mathmatics point of view, you have two variables that are not constant, velocity and acceleration

Answer 6

Assuming this could be done without dying, you would oscillate back and forth between the two poles with a time period of approximately 42 minutes during the first oscillation. The period would get increasingly smaller until you came to rest in the center of the earth.

Answer 7

well you'd fall towards the center, zoom past the center and pop out the other side (barely) start falling back towards the center and yo yo like that until you slowly came to a rest in the exact center of the earth floating helplessly. See all the mass (what you need for gravity) would be surrounding you so the forces would be equal.

Answer 8

I know that you want to hear something like 'you'd pop out a hole in the ground in china' or something along those lines...I'm afraid all that would happen is that you would die. The centre of the earth is molten rock which would burn you up..

Answer 9

This is more of a question for geology or physics, rather than mathematics. Regardless, you couldn't make such a hole. At some point you reach magma, which begs the question of how you make a "hole" in something that's liquid. But ignoring other factors (breatheable atmosphere, walls not collapsing, whether or not the hole goes through the center, etc.) you can in fact use math to show that your speed sould eventually slow down and then you'd oscillate:

Answer 10

You'd be subjected to intense pressure and heat and would die long before you got anywhere near the centre of the Earth.
