agitation

Agitation is the act of stirring things up, like the agitation of a washing machine that moves the water, detergent, and clothes around and gets the dirt out or the agitation of political activists who want people to work together to do something.

The verb agitation comes from the Latin word agitare, meaning “move to and fro.” Agitation can happen whenever something is physically moved around, like stirring flour, eggs and milk to make pancake batter. Agitation also describes feeling stirred up emotionally — upset — or moved to act, like the agitation of protesters whose signs about unfair hiring practices at a store make many shoppers go somewhere else.
