The author delves into the physics of flight, focusing on the forces generated by the flow of air around an aircraft’s wings, specifically the shape of an airfoil. Through interactive demonstrations, the article explains how different properties of air affect the motion of flowing matter, using arrows to represent the velocity of airflow. By examining individual particles of air and exploring relative motion, the author demonstrates how winds and the movement of air are perceived differently from varying perspectives. The unique perspective of motion in a windless environment and the effect of objects like cars and airplanes on the surrounding air are highlighted, making the complex topic of aerodynamics more accessible.
