Supersonic Meaning: Definition, Examples, and Translations

🚀
Add to dictionary

supersonic

[ˌsuːpərˈsɒnɪk ]

Definition

Context #1 | Adjective

speed category

Supersonic refers to speeds that exceed the speed of sound, which is approximately 343 meters per second or 1,125 feet per second at sea level under standard conditions. It is a term often used in aerospace and aviation to describe aircraft or projectiles that can travel faster than sound. Supersonic speeds create shock waves that can lead to a sonic boom when the object surpasses the speed of sound. The term is crucial in discussions of both civilian and military aviation technology, as well as in the study of various supersonic flight aspects.

Synonyms

hypersonic, transonic.

Examples of usage

  • The supersonic jet flew across the sky.
  • They developed a supersonic missile for military use.
  • The concert featured a supersonic performance with sound effects.

Interesting Facts

Science

  • Sound travels at about 343 meters per second (1,125 feet per second) at sea level and at standard conditions.
  • When an object exceeds this speed, it creates a sonic boom, a loud sound from the pressure waves it generates.

Technology

  • Supersonic aircraft, like the Concorde, could travel over twice the speed of sound, drastically reducing flight times.
  • Recent developments are exploring new designs for supersonic passenger jets that could return to commercial use.

Pop Culture

  • In movies and games, supersonic speeds are often depicted with futuristic vehicles that can move faster than the eye can see.
  • Characters like Speed Racer emphasize the thrilling idea of moving at incredible speeds, often associated with racing and adventure.

Physics

  • The phenomenon of shock waves is integral to understanding supersonic movement, as they occur when an object breaks the sound barrier.
  • Scientists study how different materials react at supersonic speeds to innovate in various fields, including aerodynamics and engineering.

Origin of 'supersonic'

Main points about word origin

  • The term 'supersonic' comes from the Latin prefix 'super', meaning 'above', and 'sonic', which relates to sound.
  • It became popular in the 20th century with advancements in aerodynamics and aircraft technology.

The term 'supersonic' originates from the Latin word 'supersonicus,' where 'super-' means 'above' and 'sonus' translates to 'sound.' The word came into use in the early 20th century, particularly in the field of aerodynamics and aviation. With the advent of faster aircraft around World War II, the necessity to describe speeds greater than that of sound led to the popularization of this term. Notably, significant events in aviation history, such as the flight of the Bell X-1, the first aircraft to break the sound barrier in 1947, contributed to the prominence of 'supersonic' in both scientific literature and public discourse. Over time, supersonic has become synonymous with advanced aeronautical engineering and is commonly associated with commercial endeavors like Concorde, which operated from 1976 to 2003, offering civilians the chance to travel at supersonic speeds.
