We all observe the things around us, but every person has his own way of observation. Some people just see the things while others focus on the solid reason behind the existence of matter or activity. However, there's some questions that most people have in their mind but can't clarify the answer.
Here I'm with the two most amazing facts of this world that'll blow your mind:
What if friction is removed from the whole world?
Have you ever observed the amazing role of friction in the world? It allows us to move or slow down.
Let's imagine the friction is removed from the whole world. The whole ground will be slippery. You will not be able to walk even a 1 cm. The most hilarious moments will occur when you will be traveling in a vehicle. You will keep on going, going, and going. You will only stop by crashing into something.
You will not be able to hold anything, even a single pin. The nails will come off and due to this buildings will fall on you. The weirdest moment will be when you will not be able to hold your glasses on your nose. Life will become unlivable.
For having that feeling, observe that you have to live on a sliding swing for your whole life. Everything will be slippery. The only benefit of removing friction is that students can calculate problems easily.
Hope friction will never remove.
Why don't we move if the Earth moves?
We know that the Earth rotates 24 hours a day. But have you ever thought about why we don't feel movement? Even the Earth's moving speed is four times faster than the world's fastest train. Then, it's strange that we don't feel.
Let's see the secret behind it.
The reason is the relative motion. The Earth is moving at the same speed all the time, and we move at the same speed as the earth moves. When we travel on a bus, we don't feel that the seats are moving because we are moving with them. But the people outside consider the seats moving because they are outside.
