Did you know that a Boeing 747 vs Airbus A380 aircraft can normally carry from 500 to 800 passengers for a trip, and weighs as much as 60 elephants, even though it flies at a very high speed, reaching nearly 1000km\/h, these giants can do it. This may make your child wonder and ask why a giant weighing hundreds of tons can fly freely like a sparrow. Let I-CLC explain to you!<\/span><\/i><\/p>\n

Before we get into the underlying causes, let\u2019s take a brief look at the forces that contribute to this phenomenon. The ability to make a massive, multi-component object like an airplane fly is due to four main forces: lift, gravity, thrust, and finally drag.\u00a0<\/span><\/i><\/p>\n

Imagine every time you have the opportunity to ride in a car, put your hand out the window and you will feel the wind pushing your hand forward. Similar to an airplane, when taking off into the air, the entire plane will be affected by a significant lifting force, it is designed to let the wind pass through to create an upward force from below – that is the lifting force. Thanks to the lifting force, an airplane can fly freely and lightly in the sky.<\/span><\/i><\/p>\n

Gravity is the force that the Earth exerts on everything around it. Imagine that if a baby wants to jump, the force of his feet pushing up must be greater than the force of the Earth’s gravity.For an airplane to fly, it must create a force greater than the Earth’s gravity to be able to fly.<\/span><\/i><\/p>\n

Similarly, thrust acts as a \u201cspring\u201d that makes the plane \u201cbounce\u201d into the air. At this point, the propellers and jets act as that \u201cspring\u201d to push the plane forward faster. Finally, drag is the force that resists the movement of the plane as it flies through the air. Imagine that you are pedaling forward on a bicycle, the further forward you go, the more you feel the wind blowing against your face in the opposite direction, that is an easy example for you to understand about drag.<\/span><\/i><\/p>\n

You know, the plane is curved above and straight below, so when the plane moves, the air has to go faster through the curved part above, and slower below. If the air goes faster, the pressure is lower and vice versa, the pressure is low above and high below the plane’s wings, so the plane can fly up.Another easy to understand example of this principle is when a child blows a piece of paper from below, the paper flies up because there is low pressure above and high pressure below.<\/span><\/i><\/p>\n

So finally you can understand the reason why this “monster driver” can fly is not thanks to the “wings” made of feathers like birds but thanks to the forces that have been formed and the principle like I-CLC. It’s so easy to understand, right? If you still want to know anything, please tell I-CLC.<\/span><\/i><\/p>\n
