A '''slipstream''' is a region behind a moving object in which a [[Wake (physics)|wake]] of [[fluid]] (typically air or water) is moving at [[velocities]] comparable to that of the moving object, relative to the ambient fluid through which the object is moving.<ref>[https://books.google.com/books?id=UzJqTX4LPOsC&dq=slipstream+aerodynamics&pg=PA415 Recent studies of Train Slipstreams by Johnson, Dalley, and Temple]</ref> The term slipstream also applies to the similar region adjacent to an object with a fluid moving around it. "Slipstreaming" or "[[drafting (aerodynamics)|drafting]]" works because of the relative motion of the fluid in the slipstream.
