Question

Explain how the wings of aeroplane are designed to help the aircraft to take off?

Answer 1

Answer:

According to a principle of aerodynamics called Bernoulli's law, fast-moving air is at lower pressure than slow-moving air, so the pressure above the wing is lower than the pressure below, and this creates the lift that powers the plane upward.
