Final answer:
To increase lift for paper airplanes, you can increase the wing area or decrease the weight of the paper airplane.
Step-by-step explanation:
To increase lift for paper airplanes, you can:
- Increase the wing area: By increasing the surface area of the wings, you create more lift. This can be done by making the wings larger or adding extensions to the wings.
- Decrease the weight of the paper airplane: Lighter paper airplanes experience less gravitational force, allowing for more lift. You can achieve this by using lighter paper or removing unnecessary weight, such as decorations or excessive folds.
