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.

よく混同される語
Aeronautics is the broad science of building and flying aircraft, while aerodynamics specifically refers to how air moves around objects.
使い方のコツ
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.
よくある間違い
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'.
覚え方のコツ
Think of 'Aero' (air) + 'Dynamics' (movement). It is the study of how 'air moves' around things.
語源
From the Greek words 'aer' (air) and 'dynamis' (power or force), emerging in the mid-19th century.
