People may have ignored something happening around us, that is friction. If there was no friction in the world one day, how would people's lives and work change?
If there was no friction, I wouldn’t be writing this article right now. Without friction between the hand and the keyboard, there is no way to type; without friction between the hand and the mouse, there is no way to click the mouse; without friction between the hand and the computer switch, there is no way to turn on the computer. If there is no friction and the computer cannot be turned on, how can we write this article?
If there is no friction one day, we will not be able to get out of bed when we wake up, no matter how hard we try; if there is no friction, we will not be able to eat at all, because our hands If there is no friction between the chopsticks and the chopsticks, you can't hold the chopsticks in your hands, and you can't even eat. If there is no friction, people can't walk normally, they will fall when they take a step, or they can't walk as fast as they want to fly. If you can't stop, it's probably better to lie down on the ground and walk. In short, if there is really no friction in life, the result must be very terrible, and even humans will not be able to survive in the world.
If there is no friction, then we cannot have a good class. If there is no friction, the tables and chairs in the classroom cannot be made. Because there is no friction between the nails and the wood, the tables and chairs cannot be nailed together, and the tables and chairs will fall apart; the teacher cannot write on the blackboard. Because there is no friction between the chalk and the blackboard, I can't stop writing lightly. I have to say it face to face. I can't even pick up the books and lecture manuscripts because there is no friction between my hands and the books and lecture manuscripts. Without friction, we would not be able to attend class, which shows the importance of friction.
If there is really no friction one day, then life will become very scary. I can’t imagine a day without friction. Of course, the absence of friction will also bring some convenience to people's lives, allowing people to easily push heavy things. Therefore, we must make full use of the beneficial friction in life and reduce harmful friction so that friction can be used by us and not become a disaster that harms life.
