In Science 10 Honors me and my group experimented with how weight placements on a paper airplane effects how it flies and how far it will travel. We did theses test by creating 3 of the same model paper airplane and giving each of them a specific colour and 2 paperclips set at different positions of each plane.
Theses 3 different weight placement consisted of pink (weight at the back), Purple (weight at the front) and blue (weight in the middle). Blue was kinda like a control but we still put weight on the plane to make all of the planes even.
I would have like to also test a 4th plane with no weight at all to see if it would fly better being lighter rather than having extra strategically placed weight.
after all of the testing we came up with the best airplane was the one with the weight placed at the tip. This is because of the aerodynamics and how the plane will be more efficient at cutting and gliding through air. The worst plane was the plane with the weight at the back because it would have the tendency to gain as much altitude as possible until it ran out of energy resulting in it flying straight down (back first) or even backwards losing distance all together.
I hope this information will be useful and educational as I know I have now learned more about the importance of weight placements in aerodynamics and flight.
