The heavier weight of a thicker paper will affect the range of the flight, and different folding characteristics and stiffness will affect the aerodynamics.
Yes, weight may affect a paper airplane by increasing its mass. This may alter its glide ratio and change its wing loading.
It allows it to take off and land
I don't know isn't there somebody to answer this?
no.because the designs just make it look better so basicly it do not affect flight
yes beacose it adds weight to the plain
Not so much the shape of the nose that affects the flight of a paper plane, but the weight. If the weight of the plane isn't distributed properly the angle of attack is too small or to large making the plane nose dive or stall. Make sure there is weight in the center of gravity of your model.
If it is too heavy, it will drop down. If it is too light, It is vulnerable to the slightest gust of wind. It is best to make it in-between(the average weight of a paper airplane)
yes. if you put it on one of the wings and try to fly it, it may tilt a little bit. it will affect the course you want it to take.
Yes, because on hot days for instance, paper airplanes can catch thermals.
duct tape will affect the flight if you use a certain amount of it because of the weight but if you only use a few pieces it shouldn't make too much of a difference
if you place a paper clip on your paper airplane, you may find it improves performance by equalizing the load (weight) and lift (what the wings generate)
