it depends on how you throw it
i think the construction paper airplane will fly farther
yes because of its weight the weight brings it down
A little bit less than a train made out of paper, but way more than a boat made out of paper. Of course, the size of the airplane wasn't stated in the question. If it was a really, really BIG paper airplane, it could weigh more than a teeny-tiny paper train. Although, if it was a tiny paper airplane it could weigh less than a HUGE paper boat. I'm pretty sure it would also depend on what kind of paper you use. A construction paper airplane would definitely weigh more than a tissue paper airplane. But one of those airplanes made out of copier paper would weigh about average. I wouldn't reccommend a toilet paper airplane. It would also depend on what kind of plane you were making out of paper. A 747 made out of tar paper is going to completely outweigh a Cessna made out of freezer paper. All in all, I would have to say a medium sized airplane made out of a mid-gauge paper would weigh in at around 3,982 kilograms.
It falls slowly because it is light, but also because the rough, flexible paper has more drag than stiffer writing paper.
Printer paper is generally more favorable because it tends to be more rigid and retains the folds better.
The shape of a paper airplane impacts its performance characteristics, including its glide range.
There are many places where one could find tutorials on building the best paper airplanes. One could try sites such as YouTube for video instructions on crafting a suitable paper airplane.
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 weight of the paper. If you accumulate a lot of paper at one place (depending on the design) it could bring the airplane down faster than if you didn't accumulate so much paper in one place.
Yes, the design of a paper airplane can effect its performance.
yes you can... but the ink would probably smear.
The number of paper airplanes possible would be a function of their individual sizes. It could be one paper airplane, or many.
