aerodynamic
air-oh-dahy-NAM-ik
/ˌɛərəʊdaɪˈnæmɪk/
Of or relating to the way air moves around objects.
Specifically refers to shapes that reduce drag and increase efficiency.
The story behind the word. A blend of the Greek 'aer' (air) and 'dynamis' (power). It’s the science of how objects move through the air with the least resistance. It became a key term with the rise of aviation and high-speed racing.
Word relationships
- streamlined: Streamlined is a more general term for a shape that reduces resistance.
- clunky: Awkwardly shaped and creating resistance.
Commonly confused with
- hydrodynamic: Aerodynamic is for air; hydrodynamic is for water.
Word family
- aerodynamics (noun): The study of air movement.
- aerodynamically (adverb): In an aerodynamic manner.
Collocations
- aerodynamic design
- aerodynamic drag
- aerodynamic efficiency
Example sentences
- "The bobsled's aerodynamic shape allows it to slice through the air with minimal resistance." Describing a bobsled's design.
- "The new suit is more aerodynamic, helping the skier shave fractions of a second off their time." A technical description of a ski suit.
Memory hook
Aero-Dynamic: Air-Power. Powering through the air. Aerodynamic = Air-friendly shape.
When not to use
Do not use for objects moving through water (that's 'hydrodynamic').
Fun facts
- Speed skaters wear skin-tight suits to be more aerodynamic.
- Even the dimples on a golf ball are an aerodynamic feature designed to reduce drag.
