When the bird saw flying, it seems, oh! If I could fly! If we had a wings like a bird, we could fly and fly. Now the question is how birds fly?
Different types of birds have different strategies. But the initial ideas are one.
The bird wings are called airfoil. When the airfoil moves in the air, the air is then carried down to the airfoil. To carry two types of air at one end of the wings at the ends of the wings, the surface of the wings above the wings should be much faster and faster than the surface below. This causes less pressure on the air surface of the surface of the upper surface and the pressure on the surface of the lower surface is more pressure. As a result, the bird goes upstairs. The faster the wings of the wings, the birds will be able to climb up as fast as possible. The bird wings are like a human hand. For cutting trees, people use their hands to fly birds using the same wings as they fly. The bird hit the wind behind the wings and the front move forward. When the bird is flying, the wings flutter. When the bird takes the wings downwards, the wind prevents the opposite direction, which leads to the surface and flies. The air pressure on the wings is less and the wind pressure under the wings is more prone to fluctuations.
