how do planes stay in air?
Answers
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.
Four forces keep an airplane in the sky. They are lift, weight, thrust and drag. Lift pushes the airplane up. The way air moves around the wings gives the airplane lift.
