How Do Airplanes Stay in the Air? explain briefly
Answers
Answer:
A plane's engines are designed to move it forward at high speed. That makes airflow 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.So it stays up in the sky.
hope so it helps if yes...plzz mark it brainliest and follow me tooo plzz
Explanation:
Planes stay in the air because of the shape of their wings. Air moving over the wing gets forced downwards, which pushes the wing up. This push is stronger than gravity, and so makes the plane fly.
This is a very technical subject that the video below deals with very nicely. Planes take advantage of Newton's third law of physics, which states that for every action, there is an equal and opposite reaction. As air moving over the wing gets forced down, there is an equal and opposing force generated. This is a combination of the bottom of the wing getting pushed up, and the top of the wing getting pulled up.
