ergon

An ergon is the unit of work or energy in the centimeter-gram-second system.

Definition

1. Noun (Physics):
   • A unit of work or energy in the centimeter-gram-second (CGS) system: Specifically, "ergon" (often shortened to "erg") is defined as the amount of work done by a force of one dyne moving an object one centimeter. It is a small unit of energy, equal to 10⁻⁷ joules.

Usage Examples

• Noun:
  • The scientist measured the energy released in the experiment in ergons. (The unit "ergon" was used to quantify the work performed.)
  • One ergon is a very small amount of energy, roughly equivalent to the work done by a mosquito taking off. (This helps illustrate the tiny scale of the unit.)

Advanced Usage

• "Ergon" is the full form of the term, but it is almost always abbreviated as "erg" in modern physics texts. The word "ergon" itself is rarely used outside of historical or highly technical contexts.
  • The older textbooks still refer to the ergon, but contemporary physics uses the erg. (The full term is now archaic in common usage.)

Variants and Related Words

• Erg (n): the standard abbreviation for ergon.

  • The energy output was 500 ergs per second. (The shortened form is used.)

• Ergometer (n): an instrument that measures work or energy, often used in exercise science.

  • The athlete trained on a stationary ergometer to measure their power output. (A device related to the concept of work.)

Synonyms

• Work unit: a general term for a measure of work.
• Energy unit: a broader category that includes ergon, joule, calorie, etc.

Related Idioms

• "Not an ergon of effort": A rare, figurative expression meaning no effort at all.
  • He didn't expend an ergon of effort on the project. (He put in absolutely no work.)

Phrasal Verbs

• Erg out (informal, rare): to expend energy or work hard.
  • We had to erg out to finish the lab report on time. (To work strenuously, derived from the unit "erg.")
