aerodynamics
Aerodynamics is the branch of physics that studies the motion of air and other gaseous fluids and the forces acting on bodies moving through them. It is primarily concerned with the forces of lift and drag that allow aircraft to fly or vehicles to move efficiently.

容易混淆的词
Aeronautics is the broad science of building and flying aircraft, while aerodynamics specifically refers to how air moves around objects.
使用说明
Aerodynamics is used as a singular noun (e.g., 'Aerodynamics is a difficult subject'), even though it ends in 's'. It is common in both technical engineering contexts and sports discussions involving speed.
常见错误
Learners often treat it as a plural word because of the 's' ending. Avoid saying 'The aerodynamics are very good'; instead, use 'The aerodynamics is very good' or 'The aerodynamic design is very good'.
记忆技巧
Think of 'Aero' (air) + 'Dynamics' (movement). It is the study of how 'air moves' around things.
词源
From the Greek words 'aer' (air) and 'dynamis' (power or force), emerging in the mid-19th century.
语法模式
文化背景
Aerodynamics became a cultural obsession in the 1930s-1950s (the Streamline Moderne era), influencing the design of everything from toasters to buildings.
