Wax paper works good for strong, high-flying planes.
I know!
gliders
I would say no.
The effect of a hole on a paper airplane would depend on the type of paper airplane the hole is on, and where it is on the aircraft.
The kind of paper chosen to make a paper airplane affects its weight. The best paper for making airplane is the light but firm paper. Firm paper prevents the paper plane from crumbling in the wind.
no
Generally, it is optimal to make a paper airplane symmetrical. I am not sure I understand what you mean by type of symmetry. However, some paper airplanes can be designed to be asymmetric and remain straight flying.
no
Well, if you want a certain TYPE of paper airplanes, and how many are there of that type, ask that. There is no real answer. A paper airplane is probably being made right now!
aerodynamics
In a paper airplane experiment, the independent variable is the factor that is being deliberately manipulated or changed by the researcher. This could be the type of paper used, the design of the paper airplane, the angle of launch, or the force applied when throwing the airplane.
