Erg
Physics Measure
An 'erg' is a tiny amount of energy, much smaller than a joule.
Her experiment released millions of ergs in only a few seconds.
Technical Term
Used mainly in scientific contexts, not in everyday conversation.
The energy emitted equaled 500 ergs.
Precision Required
When discussing work or energy in physics, precision is key, so use 'ergs' accurately.
That small reaction yielded about 150 ergs.
