Final answer:
Leonard is interested in finding the best paper for paper airplanes, which falls under the subject of engineering, specifically paper engineering. The history of papermaking and its evolution suggest that lighter and stronger papers are preferred for making paper airplanes, as they can influence the flight performance. Sanjay's experiment with different paper weights can help determine the best option.
Step-by-step explanation:
The Best Paper for Paper Airplanes
Leonard wants to know what type of paper makes the best paper airplane. The suitable type of paper for a paper airplane is influenced by paper engineering knowledge. Light and strong papers, like those obtained through traditional papermaking processes, tend to perform well. In Sanjay’s case, he conducted an experiment by making paper airplanes using three different weights of paper: light, medium, and heavy. After launching them, the distances flown could help determine which weight is best for flight performance.
The papermaking art developed in ancient China utilizes natural fibers and durable materials that could influence paper airplane qualities. The Chinese made advancements in papermaking by adding materials to the pulp, like hemp and fishing nets, to create a durable and lightweight paper called parchment. This type of paper could potentially excel in the construction of paper airplanes.
Historical evidence, such as Leonardo da Vinci’s journals, show that lightweight papers were preferred for designing flying machines. Similarly, the construction of model airplanes has evolved from balsa wood to modern plastics, but paper was a key covering material during the early days due to its lightweight nature, indicating that paper choice is critical in aerodynamics.
