How does an Airplane Fly?
Simply stated, there are four forces which are acting on an airplane.
Lift: This force is generated because of the forward motion of the airplane through air.
Drag: This force is generated because of the resistance of the air to the forward motion of the airplane.
Weight: This force is generated because of the pull of gravity towards the center of the Earth.
and finally Thrust: This force is generated by the engines of the airplane.
Now, when the force of Thrust produced by the engines is greater than the force of Drag produced due to air resistance, the airplane moves forward.
Also, when the force of Lift produced due to forward motion is greater than the force of weight produced due to gravity, the airplane moves upward.
In simple terms this is how an airplane flies.
