Drag can be reduced by flying at higher altitudes, where the air is thinner. Drag increases with speed as well, and some friction is unavoidable when generating lift.
To reduce drag in design, the exterior should be as smooth as possible, and external protrusions should be faired into the body, creating the smallest possible cross section as seen from the nose (direction of motion).

In which way you change by taskbar on the left?
drag it
Which of these best describes a flight that is approaching the speed of sound?
more drag is created because the air molecules are not moving out of the way of the airplane
Why does an airplane look the way it looks?
Because that how it needs to look to function well. Air drag, lift, passenger/cargo space, engines etc.
How is a paper plane affected by its shape?
A paper airplane is affected by its shape in just about every way. Drag, efficiency and performance are all affected by the aircraft's shape.
Role of technology of World War 1?
Many weapons were developed. One was the tank and the airplane . Both of these would change the way the war was fought.
Why a heavier paper airplane fly further than a lighter paper airplane?
The answer to this question is a matter of some fairly simple physics which I will try to explain to you. First, you need to understand that most paper airplanes are not really airplanes. Airplanes fly because the shape of the wing produces lift; paper airplanes mostly fly as projectiles, meaning that they fly because you throw them. The first reason that the lighter airplane might not fly as far is in the design. Typically, the lighter paper airplane will have larger wings, and therefore, more drag. Since it is virtually impossible to make the paper airplane perfectly symmetrical, one of the wings has more drag which causes the airplane to spin and crash short of its maximum possible distance. The second reason is also related to the design. If you have a light airplane with more drag and a heavy airplane with less drag, the heavy airplane can fly much more easily. This is because the heavier airplane has less drag as well as more momentum to "push" through the air. On this note, a piece of paper crumpled into a ball will fly further than most paper airplanes I have seen just because is has lots of mass for the level of drag it induces. The crumpled piece of paper also will probably fly much straighter that the paper airplane too, just because it is fairly uniform in shape. At this point, we are completely ignoring lift; but at such a small scale with such light material, it works better that way due to the reasons above. Of course, if you put engines and control surfaces on the paper structure, you change the game entirely. Now it has to fly with lift instead of as a projectile otherwise it will crash because it has no control. This explains why real airplanes are not just big balls of metal.

What is the definition of drag coefficient?
Simply put, the coefficient of drag (Cd) is a way to quantify the various factors that affect, and result in, drag on an aerodynamic object. See the link below for an excellent discussion of drag coefficient on the NASA website. An airplane has 4 forces acting upon it and one of them is Drag, a force in the opposite direction of flight. Aeronautical engineers study the forces on a wing but found it easier to use non-dimensional measuresments. Drag is measure in Force (lbs). But Drag Coefficient is a value of force/force. This allows the engineer to produce charts for the numerous airfoil wing designs and have a Drag Coeffecient Chart that can be used for various sizes of wing applications.
How does aerodynamics work on airplanes?
The wings push air down, creating lift. Aerodynamic force causes drag and thrust to keep the airplane steady. They have to be made a certain way (aerodynamic) for this to work.
