How do airplanes stay up in the air without falling?

Answer 1

The turbines under the wings of the airplane suck air in, mix it with fuel, and then compress the air/fuel mixture. As the compressed mixture exits the engine, it burns hotly, creating a lot of thrust backwards, pushing the plane forward and overcoming drag. As the plane moves forward air moving over the wings and pushing up on the bottom creates lift to keep gravity from pulling the plane down. This happens throughout the whole flight of the plane. The continuous cycle of pushing air backwards with tremendous force and creating lift with the wings keeps the airplane up.

Answer 2

Airplanes stay in the air due to the principle of lift generated by their wings. As the airplane moves forward, the shape of the wing causes air pressure to be lower above the wing and higher below, creating lift. Additionally, the engines provide thrust to move the airplane forward, allowing it to maintain its altitude.
