Technical

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.
