Erg
noun
A unit of work or energy, in physics, equal to the work done by a force of one dyne when its point of application moves one centimeter in the direction of action of the force.

Pro Tip 1/3Physics 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.
Pro Tip 2/3Technical Term
Used mainly in scientific contexts, not in everyday conversation.
The energy emitted equaled 500 ergs.
Pro Tip 3/3Precision Required
When discussing work or energy in physics, precision is key, so use 'ergs' accurately.
That small reaction yielded about 150 ergs.
