have you ever seen birds fly in a v? the drag from the leader pushes the other birds faster. so it kinda swirls

How is drag used on an airplane?
Lift is equal to drag, so if the drag was 12000N (newtons) the lift would be 12000N. it is mainly used for slowing the aircraft down for decend.
Why jet engines are used at high altitudes?
For thrust. Engines are used to overcome the drag of the airplane.
What propulsion improved airplane flight?
Jet propulsion improved airplane flights. Before that piston engines were used. They were much slower compared to the jet engine.
What are the flaps on an airplane used for?
The flaps on an airplane are there for two reasons: Drag and lift. As an airplane lines up with the runway and descends, it must slow down. Several things are done to slow down, such as throttle the engines down and lower the gear. However is some airplanes, to slow down and remain slow they must extend the flaps. These cause extra drag, which slows the airplane down. They are usually extended in increments while on approach. The second reason is for lift. As an airplane get slower, the wings get less and less effective, and once it gets slow enough, it may stall. To prevent a stall, airplanes lower flaps. These redirect air downward, pushing the airplane up. This allows it to fly slower, past its "clean" stall speed. (Clean stall speed refers to an airplane's stall speed with no flaps or landing gear extended) Some airplanes can fly nearly 100 knots slower with full flaps. The stall speed with full flaps and landing gear extended is known as "dirty" or "landing configuration" stall speed. This is much slower than "clean" stall speed.
Where are the flaps on a plane?
They are on the trailing edge of the wings. They are used to increase drag and can increase lift. If set to a large enough angle the amount of drag exceeds the added lift and allows a plane to land a slow down in a shorter distance than it could in a no flap condition. Flaps assist on allowing an airplane to fly at a slower speed and maintain lift and control.
How can you race the speed of light?
What do you mean, make it faster? In a vacuum, light travels at only one speed. There is no way to make it faster or slower. In other materials, light is usually slower. There are instances where it is actually measured to be faster, but it is generally believed that this can't be used to transfer matter, energy, or information, faster than the speed of light.
What is the airplane that the Wright brothers used?
It was a small bi plane. Biplane are planes that have two wings. This plane's design was not aerodynamic. It created much drag.
How does a airplane work?
An airplane is a machine used to fly. An airplane uses it's engine to produce thrust to move the aircraft. When an airplane takes off the engine(s) push the aircraft faster and faster. At a certain speed there is enough air flowing over the wings at a high enough speed for the wings to produce lift. Lift pushes the aircraft into the air and keeps it there. When an airplane goes to slow or is pointed at too great and angle, it's stalls, and falls out of the sky. Airplanes are used to carry people and goods over great distances faster and cheaper than many other forms of transport.
Why are airplane flaps not used at cruising speeds?
Because although flaps create extra lift they also produce a lot of extra drag which makes the plane inefficient.
Is enzymes slow the rate of reaction?
Actually, enzymes are typically used to catalyse a biological reaction, leading to a faster reaction rate, not slower.
What is the shape of an airplane and why does this have this shape?
The commonly used fuselage shape allows the aeroplane to move forward through the air at a reduced drag. And the sectional shape of the wings create lift.
In swimming what is the relationship between drag and swimming?
Well "drag" is usually used to describe something that will slow you, like a drag suit worn over a jammer or Fastskins, or simply wearing another suit. Swimming without that will not slow you at all, therefore in practice swimmers use drag to improve and go faster in meets.
