Just adding weight will not make a paper airplane fly farther. However, adding weight in exactly the right places can make it fly farther, by improving its balance and stability.
NO it does not.
i think the construction paper airplane will fly farther
no
Farther than any other paper airplane that i know of
Yes, the design of a paper airplane cane help it to fly farther. The more aerodynamic the design, the better the plane will fly.
Yes. A wider winspan will make a paper airplane fly farther.
throw it in the wind
yes. == ==
yes because of its weight the weight brings it down
the smallest airplane will fly the farthest
yes, the less heavy air planes float more then fly, the heavier ones fly farther then the less heavy ones.
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)
if its a basic airplane, adding paper clips to the wings can help so it doesnt just fly in random directions.
