How does Airplanes produce Lift? and why Lift force is important for Flying?
Answers
Answer:
A plane's engines are designed to move it forward at high speed. That makes air flow rapidly over the wings, which throw the air down toward the ground, generating an upward force called lift that overcomes the plane's weight and holds it in the sky. ... The wings force the air downward and that pushes the plane upward.

Answer:
In an air craft, lift is created by the flow of air over an airfoil. The shape of an airfoil causes air to flow faster on top than on bottom. The fast flowing air decreases the surrounding air pressure. Because the air pressure is greater below the airfoil than above, a resulting lift force is created. This whole process is an application of Bernoulii's Theoram. Lift force is important for Flying because in order for an aircraft to rise into the air, a force must be created that equals or exceeds the force of gravity.
