What happenes when you increase an airplanes wing size and speed?
generates more lifting force
The lifting force on an airplane's wing does what?
increases with speed
Is the upward force on a airplane wing is thrust?
Thrust is the forward motion of the airplane provided by the engines. Lift is the upward force on an airplanes wing.
What does the lifting force on an airplane wing do?
increases with speed
What is a Fixed Wing Airplane?
A fixed-wing aircraft is an aircraft which has wings that are attached to the aircraft and do not move. The term is used to differentiate airplanes from other types of flying vehicles such as lifting-body aircraft (balloons and blimps) or rotary aircraft such as helicopters and auto gyros. All airplanes are considered fixed-wing aircraft and even swing-wing or otherwise moving-wing airplanes are usually referred to as being in the fixed-wing category of aircraft.

Bernoulli's equation and an airplane's wing?
Bernoulli's equations explain 100% of the lifting force created by wings. But Newton's third law also explains 100% of the lifting force. This should not be suprising, since Bernoulli's equations are based on Newton's laws. Bernoulli and Newton are two different ways of explaining a complicated situation. Neither is more "right" than the other. If we choose one explanation while ignoring the other, then our understanding of flight will be incomplete. To be clearer... Bernoulli's equation describes the lifting force in terms of pressures applied to the wing surface. There are no other forces involved. If we know the pattern of pressures, then we know the lifting force. Yet the explanation of flight remains incomplete. Wings feel pressure because they change the motion of the surrounding "parcels" of air, and air has mass. If a wing applies a force which causes air to accelerate downwards, then by Newton's 2nd and 3rd laws, the wing must experience an equal upwards lifting force. If we know the acceleration of the air surrounding the wing, then we know the lifting force.
What does airplane swing contribute to the lifting force force on an airplane?
When the wing is straight it creates more 'lift' . When swept it allows more speed.
Why doesn't an airplane fall?
Airplanes do not "fall" because the lift from the wings is enough to counteract the force of gravity. Because of the shape of the wing, there is lower pressure above the wing and higher pressure below.
What was World War I airplanes?
There were many different airplanes developed during the war - bombers and fighters. They came in single wing (monoplanes), two wing (biplanes) and three wing (triplane) varieties.
