## What if you dug a hole through the Earth and jumped in?

If you jumped into the tunnel, you’d fall down towards the center of the Earth, accelerating constantly, thanks to gravity. By the time you reached the halfway point, after falling for 21 minutes, you’d be traveling at 28,000 kilometers per hour.

## How long would it take to fall through the center of the Earth?

42 minutes
The acceleration of gravity is 9.8m/s2 and the radius of the Earth is 6.378 million meters. This means that you would fall through the entire Earth in only 42 minutes! Can you imagine traveling 8 thousand miles in less than an hour? You maximum velocity at the center would be roughly 8km/s (18,000 mph).

Is Earth’s orbit simple harmonic motion?

it is periodic but not linear. The orbit is an ellipse, not a circle. So neither the position nor the velocity exactly describe a sine wave, so its not simple harmonic motion.

### What’s the deepest we’ve dug into the earth?

Kola Superdeep Borehole
This is the Kola Superdeep Borehole, the deepest manmade hole on Earth and deepest artificial point on Earth. The 40,230ft-deep (12.2km) construction is so deep that locals swear you can hear the screams of souls tortured in hell.

### What would happen if you fell through the Earth?

What Would Happen if You Fell Through the Earth, and Other Burning Questions. Of course, falling all the way through the Earth is impossible, since its core is molten. As you approached the center of the earth the pull of gravity would decline and eventually (at the center) cease, but inertia would keep you going.

Can you fall of the Earth?

It will fall and land on the floor. A force called gravity is pulling you down towards the centre of the Earth. Anything with mass also has gravity, the more mass something has, the stronger the pull of gravity.

#### What would happen if you fell through the center of the Earth?

Just getting to the center of the Earth and surviving is impossible. The Earth’s core is about 9,000°F—as hot as the sun’s surface—and would instantly roast anyone who found himself there. Then there’s the pressure, which can reach roughly three million times that on the Earth’s surface and would crush you.

#### What would happen if you dig to the center of the Earth?

The strength of gravity at the center of earth is zero because there are equal amounts of matter in all directions, all exerting an equal gravitational pull. With such thick air, you eventually lose momentum and stop your yo-yo motion about the center of the earth. You end up stuck floating at the center of the earth.

What motion of the Earth is involved?

Earth’s Rotation Earth spins around its axis, just as a top spins around its spindle. This spinning movement is called Earth’s rotation. At the same time that the Earth spins on its axis, it also orbits, or revolves around the Sun. This movement is called revolution.

## What would happen if you jumped into a tunnel from Earth?

A tunnel, dug from one side of the Earth to the other would be, on average, 12,742 km. So it’s a shorter trip, sure, but that’s not the best part. If you jumped into the tunnel, you’d fall down towards the center of the Earth, accelerating constantly, thanks to gravity.

## What is the motion of the ball in the tunnel?

A ball is dropped from a height h in the tunnel. The motion will be periodic with time period: A tunnel is made across the earth passing through its centre. A ball is dropped from a height h in the tunnel. The motion will be periodic with time period:

How does the mass move in a tunnel?

The force on a mass in the tunnel is along the displacement vector from the center of earth to the mass, but the component perpendicular to the tunnel is balanced by the normal force from the walls of the tunnel, and only the component of the displacement vector parallel to the tunnel is responsible for accelerating the mass.

### How long does it take to dig a tunnel across the Earth?

A tunnel, dug from one side of the Earth to the other would be, on average, 12,742 km. So it’s a shorter trip, sure, but that’s not the best part.
