Why don t we feel the earth turning

Relatively still, there is a piece of information to look at.

Because the earth is too big, and we are rotating with the earth, everything around us is moving with the earth, in physics this is called relative stationary, just like we take a train and a car, we and our passengers are speeding with the train and car, if we don't look out the window at the creatures, we will feel that we are not moving. That's the truth, back to the first sentence, the earth is so big that we can't see the creatures "outside the window", so we can't feel it.

I'm sorry to retort to everyone, we and the earth can't be said to be relatively static. Why? Because the concept of relative rest is in an inertial frame of reference, such as in a train or a car, how can it be understood.

However, it should be noted that when the train and car are moving in a straight line at a uniform speed, this is the case, if they turn around, accelerate and decelerate, we will all feel the movement trend relative to the car.

Being on Earth is like turning a corner in a car, the Earth is constantly turning, so the direction of our velocity changes all the time, so we are in a non-inertial frame of reference. This is a non-inertial force that we will receive, but this force is too small for us to feel ... Although we don't feel it, some natural phenomena can be observed, such as cyclones, and the rotation of the wind is related to the forces on the earth (and of course, there are other relationships).

Because I've been spinning all the time.

It's like if you sit on an airplane and the wind won't blow you, everything around you will move with you.

Yes, that's relative stillness.

It should be said that the selected reference object is relatively stationary with the person.

The earth is constantly turning, why can't we feel it when we live on it? Our Earth experiences different rotational speeds in different geographical locations, with the equatorial rotational speed being the fastest, reaching 456 meters per second. Most of the Mars and satellites are launched here.

The Shanghai Floating Train is the fastest commercial train in the world, running at 400 kilometers per hour, equivalent to 110 meters per second, but it does not reach a quarter of the speed near the equator. So why do we live on Earth without feeling that the Earth is spinning? Because the Earth is rotating at a constant speed, which means that its speed of rotation does not change, and those of us who live above the surface are moving at the same speed, which is why we don't feel that it is rotating.

That's why we jump in the air and still land at the origin, like on the high-speed train, you jump and still fall in place.

There are three reasons why we don't feel the Earth turning, and here are the following, because we are so small. It's like we're on a speeding bus, and if we compare it with the scene outside, we're moving forward.

But if we compare it with the people around us, then we are stationary, from which we can understand that the earth is obviously rotating, but we can't feel its changes relative to the environment in the earth, so it shows how big the earth is and how small human beings are.

Introduction:

The second is the rotation of the water current, and it is often seen that some vortices will occur on the surface of some lakes, usually because the water plug on it may have been pulled out, or the water has accumulated to a certain point and then began to leak.

Then this vortex is related to the direction of rotation of the earth, depending on whether the time of the earth is clockwise or counterclockwise from the southern hemisphere, it depends on whether the vortex is clockwise or counterclockwise.

The third is to look at the garbage on the river, there is usually a little garbage floating on the river, and here we also want to accuse people of not protecting the environment, whether the garbage is blown to the lake by the wind, or directly thrown into it by man, it is our mistake.

Because there is no reference. On a high-speed train at 300 kilometers per hour (with the windows closed), we don't feel the speed of the high-speed train, and we don't feel the speed on an airplane traveling at 700 kilometers per hour. If we think of the Earth as a "high-speed railway" in the universe, if there is a fast-moving scenery next to its orbit, we can easily feel the movement of the Earth.

But there's nothing like that up close.

We also don't have a way to put a nail in space as an absolute reference. As a result, it is only possible to rely on distant celestial bodies that appear to be stationary as references. In fact, those celestial bodies are by no means "nails in space", but because they are so far away, we might as well – and probably the only option – these distant stars as references.

Therefore, when an object is not acted upon by an external force, it will always remain in motion. This is also the content of Newton's first law.

Another reason why people can't feel the rotation of the earth is that the earth rotates too slowly and the angular velocity is too low relative to the volume of the earth. It takes a day to make one revolution, and a year to complete one revolution. There are some neutron stars in the universe that can rotate hundreds of times a second, and if the angular velocity of the Earth's rotation increases to a certain extent, people can feel the rotation of the Earth.
