Increasing an airplane's speed or wing size does which of the following?
Generates more lifting force
Which states Bernoulli's principle?
Bernoulli's principle states that an increase in the speed of a liquid results in a decrease in pressure, and a decrease in the speed of a liquid results in an increase in pressure. This principle can be used to explain why airplanes are able to gain lift and fly. The wing of an airplane is designed to allow air to move at a faster speed over the top of the wing and a relatively slower speed across the bottom of the wing. This differential in the speed of the air over the wing and beneath the wing results in a low pressure above the wing and high pressure below the wing, causing lift and allowing the plane to fly.
Whats the relationship between speed and lift?
Lift is proportional to the density of the air and approximately proportional to the square of the flow speed. Lift also depends on the size of the wing, being generally proportional to the wing's area projected in the lift direction.
What is the angle between the airplanes wing and the direction of airflow called?
This is called the "angle of attack."
How does faster-moving air affect air pressure?
Air traveling at a high speed has less air pressure. This is how airplanes are able to generate lift. The top of the wing is curved and forces the air to move faster (by making it travel farther in the same amount of time) than the air below the wing.
What happenes when you increase an airplanes wing size and speed?
generates more lifting force
What happens when your Increasing an airplane's speed or wing size?
Greater lift
increasing an airplane's speed or wing size does which of the following?
Generates more lifting force
Increasing an airplane's speed or wing size does which of the following?
Generates more lifting force
How do airplanes come down?
They reduce engine speed and extend 'flaps' which allows the wing to keep lift at lower speed.

Five factor that affect aerodynamic lift?
Shape as in the curvature of the wing (camber), Size as in the wing's size, Speed,Thrust , the weight of the aircraft, may be drag too.
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.
What kind of plane is the delta wing design on?
The kind of plane that have delta are the airplanes that fly very fast, usually over or near the supersonic speed (faster than the speed of sound). The type of airplanes that have the most delta wings are fighters, and some of the bombers such as the XB-70.
What doesnt affect the amount of lift on an airplanes wing?
The best way to answer this question would be to say what does effect the lift of a wing. Pretty much the only things that effect the lift of a wing are the density of the air over the wing, the surface area of the wing, the speed of air over the wing and the angle of attack. Everything else has no effect on the amount of lift on a wing.
What does airplanes have?
wings engine and body.Also wing tips
What is the use of flaps in airplanes?
Flaps increase the aerodynamic lift of a wing by increasing it's surface area. This allows the airplane to generate a greater amount of lift at slower speeds. In other words, when the flaps are extended, the airplane doesn't have to go as fast in order to take off or land. The flaps are retracted once the airplane is off the ground and has increased its speed to a point where the extra lift from the flaps is no longer needed. Flaps also have the effect of increasing drag on the airplane wing which reduces the airplane's speed and efficiency, but this only affects the aircraft when operating at higher speeds.
