Why don't we feel that the Earth is spinning?

Earth's rotation speed at the equator is about 1,657km / h. But why don't we feel that the Earth is spinning?

Many of us know that Earth, including the atmosphere and everything on the planet's surface, is still spinning. According to calculations, at the equator, Earth's rotation speed is about 1,657km / h. That means, if you stand at the equator, you're moving at 465m / s.

What many people wonder is, why don't we feel this. The answer lies in the natural movement of the Earth.

Imagine you're on a plane flying in the sky with a certain speed and altitude. You can still remove your seat belt and travel on the plane, however, you cannot feel the movement of the plane.

The cause is simple: You, the plane and everything inside the plane are moving at the same speed. To feel the movement of the plane, you have to look out at the clouds outside the window.

The Earth rotates continuously because nothing stops it.

Feeling the movement on the plane is similar to the movement of the Earth. Our planet revolves around its axis (Earth takes about 23 hours 56 minutes to complete a rotation) and just as you cannot feel the movement of an airplane, you cannot feel it. be the fact that the Earth is moving.

The only way for you to feel the movement is the wind hitting the face . However, remember, the entire Earth atmosphere also moves at the same speed as us.

If the Earth changes speed, you can feel this movement completely. However, it will not be pleasant at all because it is a sudden brake at the planetary level while the atmosphere will still travel at 465m / s and sweep on the surface of the Earth.

So why does our Earth turn so continuously? The reason is simply that nothing stops it . When our Solar System was created, all the planets turned inertia and billions of years later they were still spinning.

To change this inertia, we need an external impact force. At that time, all trajectories will change and everything will fall into chaos.

In addition, the speed of the Earth is not a constant but it is rotating slowly due to the gravity of the Moon . According to calculations, every day, the Earth turns slowly about 2 / 1,000 seconds.

This is the reason that sometimes one has to add a leap second to the clock to synchronize Earth's time and atomic time. However, this change is so small that for us, the Earth is still rotating at a constant speed.
