There are four. Lift, drag, gravity and thrust. Let's break it down. Thrust comes from the engines. Either the drives are attached to the wing or to the body of the craft and thus to the wing. Thrust moves the aircraft (and its wing) forward. Drag is the aerodynamic resistance of the wing. The air cannot flow perfectly around the foil, so drag is created along the top and bottom surfaces. There is a good supply of drag on the leading edge of the wing, too. Gravity pulls the wing down (along with the rest of the craft). Lift is last. It has two components. One is kite effect. We know how a kite works. Air pushing against the "slanted" bottom of the kite pushes it up and back. The string limits back movement, so up it goes. (The "up" angle is called the angle of attack, by the way.) The engines force the plane forward into the air, and the air pressure on the underside of the wing forces it up like with a kite. Obviously if the wing is tipped down, there will be kite effect in the down direction (negative angle of attack). The second component of lift is Bernoulli's principle. Owing to the shape of the wing, air flowing over the top moves more quickly than air along the bottom, and Bernoulli said that moving fluids have less pressure than stationary (or slower moving) fluids. Lower air pressure on top of the wing translates into lift.

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.
Are airplanes aircraft?
Yes, airplanes are aircraft. However, not all aircraft are airplanes. Helicopters, blimps, and balloons are aircraft- but they are not airplanes. Airplanes are generally fixed wing machines that move through the air.
Airplanes and aircraft?
Airplanes are generally fixed-wing aircraft. Aircraft can mean any type of flying machine, from airships (balloons/blimps), jets, propeller driven airplanes, rotor-wing (helicopters), UAVs (Unmanned Aerial Vehicles), drones (about the same thing as a UAV), or the space shuttle.
Forces that act at a distance?
Those include electrical forces, magnetic forces, and gravitation.
By the Lend-Lease Act America sent weapons ammunition tanks and airplanes to Britain?
True

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.
How do airoplans fly?
The common answer is that air flowing over the top speeds up because of the camber of the wing, this sped up air causes low pressure on top of the wing which causes the wing to 'lift'. This is true but also the angle of attack of the wing to the relative airflow forces airflow down, which also in turn pushes the wing up. This can be shown simply by the fact that aerobatic airplanes with symmetrical airfoils fly just fine (with no camber whatsoever). So it is a combination of low pressure on top of the wing and the angle of attack of the wing forcing airflow down, which forces the wing up.
What do you call a group of airplanes in formation?
A flight, a squadron or a wing.
Do airplanes usually have 2 wings?
Yes, airplanes usually have 2 wings. 1 wing would be unsteady.
How do airplanes flya?
They way airplanes fly is actually very simple. The wing of an airplane is curved on the top and flat on the bottom. This means that the top side of the wing is longer than the bottom part. When air passes by the wing, some of the air goes on top and some on the bottom. Because the particles of air want to stay together by the law of attraction, the air that passes over the top of the wing moves faster than the air that flows under the wing. This causes a low pressure system to form above the wing and a high pressure system to form below the wing. The higher pressure beneath the wing forces the wing up allowing the air plane to fly. This is also called Bernoullis principle.
Airplanes and aircraft?
Airplanes are generally fixed-wing aircraft. Aircraft can mean any type of flying machine, from airships (balloons/blimps), jets, propeller driven airplanes, rotor-wing (helicopters), UAVs (Unmanned Aerial Vehicles), drones (about the same thing as a UAV), or the space shuttle.
Can an airplane go to space?
No. Airplanes need air to fly. The wing shape when passing through the air, creates more pressure on the bottom of the wing than on the top creating lift. In space there is no air and so airplanes will not work.
What is a delta wing?
Delta wing is the swept back wing design seen on jet airplanes like the Concorde. It is also a race car used in Le Mans in 2012.
Why red light on left wing tip and green on right wing tip?
so other airplanes in the sky can differentiate your direction of flight.
