The hole of the earth.

The hole of the earth:

Occasionally I wish to visit all the amazing places of my earth. Well if a traveler. What would have happened if there was a hole in the corner? So we are few from one country to another. I could leave in minutes. But is that possible? Many would say hey it's impossible. Because below the surface. There are lots of lava and water. Well if it seems like there is none of this, is that even possible? Think a little below. Start reading the side text.

The truth is that this is not possible. The main reason is gravity. We know that the attraction between the earth and the angle is the gravity. Now you might think this is the hole we have to go through. You are right. Will help But we know this attraction is the center of earth. Works from Then you can understand what will happen. You can go right up to the middle of the earth. But that's where the real fun started. Once upon a time you would be digging. Because the center pulls it on both sides of you. Then the event will stand on the surface of the earth where you are. Gravity will force you to tirelessly. But as you move to another page, you start to reverse. After a while the opposite will pull you back into gravity. In this way, life will continue if not forever. You have to apply an external force to the corner. The thing is a bit rocky. In the words of substance. Is called the periodic motion.

Now let's talk about an interesting one.

What happens if you take a few drops of cotton and some iron from 100 feet high?

The matter is very straightforward. This is due to gravitational acceleration. People who think like this are all mistaken. This is because gravitational acceleration does not depend on the mass of the object. Therefore, the gravitational acceleration acting on heavy and light objects is the same. Then they have to reach the ground together? But why not fall? The reason for this is the air barrier. The difference between the fall time for heavy and light objects is the difference in wind resistance. Scientist Galileo showed various objects from the roof of a high-quality temple, showing that they reached the ground at about the same time. They would fall to the ground together without air barriers. What a joke then! Iron and cotton will fall to the ground at the same time!

So, at the end, let me make a fun question.

If 100 kg of cotton and 100 kg of iron are thrown together, which one will fall on the ground first?
