Pro Tip

Distinguishing meanings

Context determines whether 'friction' refers to physical resistance (e.g., 'engine friction') or social tension (e.g., 'workplace friction'). Look for clues like 'lubricant' (physical) or 'team meeting' (social).

Gold Rule

Technical vs. metaphorical use

In engineering, friction is a measurable force. In psychology/sociology, it describes emotional or social resistance. Never mix the two in formal writing.

Word Origin

From Latin 'frictio' (rubbing), from 'fricare' (to rub), via Old French 'friction'. First recorded in English in the 16th century.

Usage Notes

In technical contexts, friction is measurable (e.g., coefficient of friction). In social contexts, it describes interpersonal or systemic conflict. Avoid confusing the two meanings in formal writing.
