For most people, the reason why planes can fly is not so obvious. Before to understand that, we need to know the Bernoulli principle.
Before further reading, you may interest in an experiment and it will help you to understand the principle better. You prepare two pieces of paper and hold them vertically. When you breath out air into the gap between paper, you will find that the two pieces of paper tend to be close.
According to the experiment, you can conclude that the faster the speed of air, the lower pressure of the air is. The Bernoulli principle says about the mathematical relationship between the velocity of air and the pressure of air. You can watch the video on the top of the blog.
It may be not easy to understand it with out daily common sense. But it does help the plane fly.
Wow, your experiment is not complex but interesting. I waant to know more about how the plane can fly, can you teach me?
ReplyDeleteAhhh, that's an interesting topic, but what you introduced are the common knowledge about plane... you could be more specific since you are so professional
