空氣動力學
研究氣體運動及物體在其中移動的科學
the branch of physics that examines how air and other gases flow around solid things, and how forces such as lift and drag act on objects moving through those gases — for example, the wings of an aircraft or the body of a racing car.

more specifically the branch dealing with forces and motion in air
文法句型
aerodynamics + singular verb
用法筆記
Frequently used as an uncountable noun with a singular verb (e.g., aerodynamics is a branch of physics). In technical writing, it may also appear with a plural verb when referring to specific sets of forces or properties.
2. the features of a design that affect how much the air pushes against an object a
氣動特性
物體形狀影響空氣阻力的特性
the features of a design that affect how much the air pushes against an object as it travels — a shape with good aerodynamics slices through the air easily, while a poor one creates drag and slows it down.
The car's poor aerodynamics created a loud whistling noise at high speed on the highway.
這輛車的氣動特性不佳，在高速公路上行駛時發出很大的呼嘯聲。
collocation: poor aerodynamics

- streamlining
refers specifically to the process of shaping an object to reduce drag, while aerodynamics describes the resulting property
- wind resistance
a narrower measure of the opposing force, whereas aerodynamics covers the overall air-flow behaviour
- drag coefficient
a precisely measured number, not a general quality; used in engineering contexts
文法句型
has/good/poor aerodynamics
用法筆記
In this sense, aerodynamics can take either a singular or plural verb depending on the focus (e.g., the car's aerodynamics is impressive vs. the car's aerodynamics are state-of-the-art). The context of vehicle or product design is the most common.
