Airplanes

Airplanes

Many of you have asked yourself how are airplanes able to fly if they are so heavy. The only way to explain this mind blowing fact is physics. An airplane has to be moving at a very high level to be able to fly. Air friction is then created and allows the plane not to fall down. An other factor are the wings. The wings allow the plane to "float" on air. They cut through the air and in a sort of way lay on air. This is also thanks to air friction. Without our atmosphere, not only we would die, we wouldn't be able to fly.

Their are many different types of planes. Each plane require different explanations to state how they work. Physics is once again essentiel to explain to phenomenas. Their are planes that have the capability to land in water. Those plans obviously need different modifications to be able to float. They now have to be light weight and use materials that won't sink. Plans who land on normal grounds have to be equipped with wheels and have to make contact with a fairly low speed to make sure they don't crash.

Planes can also reach speeds faster than the speed of sound. They have engines engineered to fly at speeds that can defy the speed of sound. Those planes are obviously lighter and more aerodynamic.

To conclude, planes require a lot of physics and are based on a lot of physics theories. They might look magical at some times, but they are not.
