If you string a hole from one end of the earth to the other and throw something down, where will it

The object vibrates in simple harmonics.

Let the mass of the object be m, the mass of the earth be m, the relative distance between the object and the center of mass of the earth be r, the radius of the earth be r, and the average density of the earth be .

Because the object is moving inside the earth, the gravitational formula cannot be used directly, and the rigid body of the earth needs to be described from the density formula. So by the formula of density = m v with the two-body gravitational formula, there is:

f=gρ(4/3)r³m/r²

Considering that g (4 3)r m is a constant and the periodicity of r change, g (4 3) r m = -k and 1 r = x

Thus, the above equation can be reduced to a simple harmonic vibration formula, f=-kx

From this, it can be seen that the object will not stop somewhere. Instead, the center of the earth is used as the center of vibration to do simple harmonic vibration.

Ideally, it should be centered on the center of the earth**.

Because the gravitational force of the earth is at the center of the earth, when things are still going down, the gravitational force of the center of the earth accelerates to the center of the earth, and when it passes the center of the earth, the direction of the force changes and slows down. It's actually shaking in the hole. (Friction is not taken into account, and it is believed that it will not touch the wall of the cave and that the cave is unobstructed and free of heat and magma).

It must have been melted down!!

It shouldn't fall to the other end If it's a hole at the poles, the object should be at that pole If it's a hole at the equator, the object should stop in the middle!!

Imagine if there is a hole in the middle of a big magnet, where will the iron ball fall if you throw it in? If the earth could make holes, theoretically it would fall to the wall of the cave near the center of the hole

If it does not melt.

Moving back and forth with the center of the earth.

High density in the middle.

Great attraction. Fall down and suck it back.

It should be given to be in the center of the earth with physics.

If you don't take into account the resistance, what is still going not to stop, it should be centered on the center of the earth and do a simple harmonic vibration.

Ideally, it's the other end.

It is the relationship between the restoring force and the displacement of the simple harmonic vibration. The block vibrates in simple harmonics, with the center of the earth in an equilibrium position, with maximum velocity, and reciprocating between the ends of the hole. There is no freeze frame

Hello, if you dig a hole in the middle of the earth to the other side of the earth, if you throw an object into it, the object will freeze in the center of the earth, so that the gravity of the object is 0!

The gravitational force f= the gravitational force of the earth's bonding surface = it has been proved in the relevant book that the gravitational force fx at any point inside the earth corresponds to the mass of m in the above equation is only the mass of the sphere inside the sphere where any point inside the earth (the blue sphere) is set to mx

It is the relationship between the restoring force and the displacement of the simple harmonic vibration. The block vibrates in simple harmony, the center of the earth is in a balanced position, and the velocity is maximum, vibrating back and forth between the two ends of the hole. There is no freeze frame

Since the earth is sphericalIf we start digging a tunnel to the ground on the other side of the world, what if we dig through it? If you jump in, can you really reach the other side of the globe? But in reality, it is unscientific to excavate such a tunnel at the moment, because it takes about 12,700 kilometers of solid rock and molten magma to dig from one end of the earth to the other.

The temperature in the center of the Earth is as high as 6,000 degrees Celsius, and the pressure in the center of the Earth is also 360 times higher than the pressure on the ground. Then,If this tunnel hole is really dug. So what's going to happen?

So what is the nature of this hole?

To avoid the Corio effect, we will:The hole passes directly through the opposite poles of the Earth, without the Corio effect, regardless of air resistance, we all jump into the hole and fall due to gravity, descending very fast, reaching kilometers per second. But when it falls near the center of the earth, something terrible happens. The mass above will begin to counteract the attractiveness of the mass belowThis means that the downward gravity will continue to weaken and continue to reach the center of the Earth, which is a terrible thing.

When reaching the center of the earth, the gravitational force is basically zero, so it will be weightless, floating in the center of the earth. Because all the gravitational pull of the earth is directed towards the center of the earth. Therefore,Even after digging through the tunnel hole, any falling object essentially loses all gravity in the center of the earth and there is no way to get out of the other end of the hole.

Why not? If we ignore the air resistance, let's say that the ball will not hit the wall if it is made in the poles, and the ball can pass through the earth to the other side due to inertia. In other words, the tunnel through the train needs to be vacuumed and constant temperature to allow the train to cross the earth with very little energy consumption!

Theoretically, it is not okay to dig an ordinary hole directly, even if you can really dig through, you will suffocate, du, die of heat, be.

Zhi melts, turns into powder, and has no gravity.

DAO levitation, even if you remove all this and change gravity to one direction, there will be gravitational acceleration to throw you out... Of course, if you're opening a wormhole that uses space folding technology, maybe you can...

Of course not. Because the earth is not hollow, there are rocks in it.

First of all, you don't dig holes in the earth, because it's all rocks. Secondly, there is magma underneath. So you can't fall to the other side of the globe.

It will take at least 2,365 years to dig up the earth, and it is too ......early to tell if you can live to that time and see it with your own eyes and try it out

You can guess with a toe that he's going to fall to the center of the earth. Gravity surrounded him. Up and down, not up and down.

You can try it, use the robot to go down the well, and the cylindrical shape will hit it with all your might. Maybe the heat can be transferred and used to explain the mystery of **, but it is almost fantastical like the moon landing.

First of all, you can't make a hole in the earth, because you go several kilometers deep, and it's full of magma, and if you jump, it will immediately turn into gas vapor. Also, if you do punch a hole through the earth, you will float in the middle of the hole where the earth's attraction is balanced, and you won't come out of the other side.

This question is interesting, I feel that the most realistic should be after falling into the hole, after the physical and chemical reaction, the person will gradually turn into a fist-sized and extremely dense ball to vibrate with the center of the earth's core, until finally, it will be stationary in the center of the core, of course, the premise of this hypothesis is that there is only air in the hole!

Because the temperature in the center of the earth is extremely high, I think that people will die of heat when they fall to the center of the earth.

If you didn't know that there was a hot magma barrier in the center of the earth, you would have said that children would have said that you would have said that you would have said that you would not have said foolish things.

Not possible, because the center of the earth will be very high.

I can't confirm it, it's pointless, you can't get this hole, it's pointless to ask.

If you dig through the earth and jump into the hole, you won't fall to the other side of the earth.

You can't jump to the opposite side of the Earth, and it's all lava underneath.

Of course, I don't think there's magma in the earth's crust.

If the hole can be dug through, and can maintain a dao state of a zhi hole (with what materials and methods to maintain and will not be discussed), and the hole is empty all the way to the opposite side of the genus (without any solid or liquid substance), it is a state of ventilation (a very wonderful hole), and the person jumps from the hole:

1 Man falls to the center of the earth, and does not fall to the other side of the earth.

2 When a person falls to a certain depth, due to the action of gravity, the density of the air increases and the temperature rises, and the person cannot bear it, and the high temperature and suffocation die.

3 When it continues to fall to a certain depth, the body will float in the air with a very high density and will not reach the center of the earth, and finally the body will slowly evaporate.

Enjoy life in the center of the earth.

If you want to jump into the hole smoothly, you can't just find a place to dig the hole, why? Because the earth is always rotating, we are also moving with the earth, but we don't feel it.

We know that the closer to the center of the earth, the slower the linear speed of its rotation, and when we jump into the hole and fall, we are essentially closer and closer to the center of the earth, but our linear speed has not changed, in this way, the linear speed of the "wall" around the hole will be slower than our own linear speed, so we will be pressed by inertia on the wall of the cave to rub, which will seriously affect our mood.

There is a special term for this phenomenon, called the "Coriolis effect". The best way to avoid the "Coriolis effect" is to dig down the Earth's axis of rotation, from the South Pole to the North Pole, and of course, if you want to dig the other way around.

Digging this hole is really hard, we need a strong drill bit, we need a material that can withstand 6,000 degrees Celsius, and the material must be unimaginably strong enough to hold the hole inside the earth, otherwise the hole will collapse in an instant.

In addition to this, we also need a special set of protective clothing that can keep our lives safe when we fall down at high speed in this hole. Anyway, now that we've dug the hole, we've installed lighting in the bottomless hole to make it easier to have fun along the way. When everything was ready, it was just time to jump, and we checked the hazmat suit one last time, and after swallowing a mouthful of saliva, jumped into the hole!

Everything is as imagined, we are under the effect of gravity, constantly accelerating and falling, with the rapid increase in speed, the surrounding lights gradually become a straight line in our eyes. Our hearts cheered and enjoyed this amazing journey to the fullest.

However, we soon found that soon after jumping into the hole, the speed of our descent suddenly ceased to increase, and as an hour passed, two hours passed, we were in this state of falling at a constant speed, and this "wonderful journey" suddenly became boring.

According to our judgment, the current speed does not seem to be very fast, the maximum speed is only more than 200 kilometers per hour, considering that the radius of the earth is 6371 kilometers, at the current speed, we need about twenty or thirty hours to reach the center of the earth. What's more, when we pass through the center of the earth, our speed will be reduced by gravity, and at such a speed, it is impossible for us to reach the opposite side of the earth!

If you dig through the earth, can people really jump into it and go to the other side of the earth?

No, because the temperature in the center of the earth is very high, and it will melt when it reaches a certain depth.

No. There is a strong pressure in the interior of the earth, and the further underground you go, the higher the temperature, and whatever the object is, it will melt.

Not being able to go to the opposite side of the Earth, i.e. when you throw a ball at the opposite side of a rotating object, the ball cannot reach the opposite side of you, or the strange trajectory of the ball on the rotating object is due to the Coriolis effect.

There is a lot of pressure in the interior of the earth, and the further you go underground, the higher the temperature, but we don't feel it.

Definitely not, and digging this hole is laborious, requiring drill bits and materials that can withstand temperatures of 6,000 degrees Celsius.

It's impossible, gravity or something, the stressful environment causes you to see that you can't even reach the bottom.

No. There is a strong pressure in the interior of the earth, and the further underground you go, the higher the pressure, the higher the temperature.

The further you go underground, the higher the pressure and the higher the temperature, and whatever the object is, it will melt.

In fact, it is impossible to dig a hole in the earth, and the deepest depth of the earth currently developed by humans is about 2 kilometers, and the thickness of the earth's crust is 33 kilometers, and it does not pass through its "skin" at all.

Theoretically, if the earth is dug through a hole, it is impossible to reach the other end through this hole, and will only stay in the middle core of the earth. Because of gravity, any object on the earth has a centripetal force that holds the object on the surface of the earth. Once out of the center of the earth, the centripetal force will change, so the falling object will return to the center of the earth.
