可以想成把手伸出行進中的車窗外，再把手掌轉個角度。空氣會推你、抬你、拖住你。這個字的兩個用法都活在那股推力裡。一個指研究這股推力的學問，另一個指某個東西面對這股推力時表現得好不好。From the word’s history
Built from aero- (air, from Ancient Greek aer) plus dynamics (from Ancient Greek dunamis, power or force): the force of air.
這個字由 aero-（空氣，來自古希臘文 ᾱ̓ήρ）加上 dynamics（力與運動，來自古希臘文 δύναμις「力量」）組成。字面就是「空氣的力」，兩個用法都是從這股力量延伸出去的。
