How Do Planes Stay Up?

An aeroplane lifts up in the air due to the huge aerodynamic lift provided by its wings. The wings are in the shape of an Airfoil. If we see the cross-section of the wing clearly, we will find that the upper surface of the wing or the airfoil is curved in shape, than the lower surface. When the aeroplane moves through the air, the air flow past around it. When this high speed flowing air strikes the upper surface of the wing, it changes its direction as well as its speed.

Though airplane flight may appear miraculous, there is science behind it. Airplanes stay up in the air because of the aerodynamic force referred to as lift. Airplane lift, generated by each part of an aircraft, is a force that works in direct opposition to the weight of an aircraft.
