- Lift is the force that directly opposes the weight of an airplane and holds the airplane in the air. Lift is generated by every part of the airplane, but most of the lift on a normal airliner is generated by the wings. Lift is a mechanical aerodynamic force produced by the motion of the airplane through the air.

The popular explanation of lift. Students of physics and aerodynamics are taught that airplanes fly as a result of Bernoulli's principle, which says that if air speeds up the pressure is lowered. Thus a wing generates lift because the air goes faster over the top creating a region of low pressure, and thus lift.
May 1, 2024 · Lift is the force that holds an aircraft in the air, countering the effect of weight (gravitational force). It is primarily generated by the motion of the air flowing around the wing. The curvature of the wing produces a differential pressure between the upper and lower surface resulting in a lifting force being generated.
Feb 28, 2024 · We can think of lift as a relationship between four elements: an increase in airflow speed over the wing, a decrease in pressure over the wing, an increase in pressure under the wing, and a downward turning of the airflow.
Lift is the force that holds an aircraft in the air. Lift can be generated by any part of the airplane, but most of the lift on a normal airliner is generated by the wings. Lift is an aerodynamic force produced by the motion of a fluid past an object.
Four Forces Affect Things That Fly: Weight is the force of gravity. It acts in a downward direction—toward the center of the Earth. Lift is the force that acts at a right angle to the direction of motion through the air. Lift is created by differences in air pressure.
Lift is the critical aerodynamic force that brings an aircraft to fly. The dynamic effect of the air moving across an airfoil produces lift. Common airfoils include not just the wings but the flaps/slats and stabilizers too.
