When an airplane flies, it must first overcome two primary forces--weight and drag. Now, find where the paper airplane balances on your finger, and add a paper clip at that point. Weight is the force of gravity acting to pull the plane to the ground, and it is overcome through lift. This means that they have a slightly upward tilt. Flight is also affected by the weight of the paper plane. The act of the Earth’s gravity pulling on the plane is the force of the weight. The weight also will cause your paper plane to land. The rear elevator wings, in particular, can be adjusted to make a paper airplane lift, dive or curve to the left or right. It's recommended that a paper airplane's wings be dihedral. The weight of the paper plane also affects its flight, pulling it down towards Earth. The heavier weight of a thicker paper will affect the range of the flight, and different folding characteristics and stiffness will affect the aerodynamics. For the short stubby design, try Cd = .4 and Cl = .8. rho = 1.23 kg/m^3 is the standard density of air at sea level. And A is the cross sectional area of the paper plane. Fly the plane and measure the distance again. All of these forces (thrust, lift, drag, and weight) affect how well a given paper plane's voyage goes. All of these forces (thrust, lift, drag and gravity) affect how well a given paper plane's voyage goes. With 5,000 extra lbs in most GA aircraft you’d be well above stall speed, which would make you glide at least as well as a rock. The weight of the paper plane also affects its flight, as gravity pulls it down toward Earth.
Now, take the best flier, and record how far it flies (measure the distance).
All bets are off when the wing stalls. The dihedral shape of a paper airplane's wings and the angle of its rear elevator flaps affect how it flies. The distance with the paper clip (the heavier plane) should fly less far then the same plane without the weight. Remember weight does affect stall speed. Weight is the force of Earth's gravity acting on the paper plane. How does gravity affect an aircraft in flight?
