Plane Wing

How planes fly ?

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. So it’s the engines that move a plane forward, while the wings move it upward.

The forces that effect on a plane are : Thrust forward caused by #engine , lift up cased by wing , drag backward caused by air resistance and weight down .

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 #force that keeps the #plane in the air
