Aerodynamics is the study of how gases, such as air, interact with solid objects, such as aircraft, cars, or buildings. It focuses on understanding and predicting the behavior of objects as they move through the air, including the forces acting on the object and how these forces affect its motion. Aerodynamics is crucial in the design and optimization of vehicles and structures to ensure optimal performance, efficiency, and safety. This field of study is essential in a wide range of industries, including aerospace, automotive, and civil engineering.
