Question

how do areoplane stay in air ?

Answer 1

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 2

Answer:

According to Yale geophysicist, Professor Ron Smith, airplanes stay in the air by shifting to maintain various states of equilibrium. It is all a matter of thrust and lifts: the amount of thrust from the engines must overcome the drag force resisting motion, while the lifting force must counteract the effects of gravity.
