what is the difference between union jack and union flag
Union Jack The terms Union Jack and Union Flag are both historically correct for describing the de facto national flag of the United Kingdom. Whether the term Union Jack applies only when used as a jack flag on a ship is a modern matter of debate.[9]
Union Jack The Union Jack,[note 1][2][3] or Union Flag, is the national flag of the United Kingdom. The flag also has an official or semi-official status in some other Commonwealth realms; for example, it is, by parliamentary resolution, a ceremonial flag in Canada and known there as the Royal Union Flag.[4] Further, it is used as an official flag in some of the smaller British overseas territories. The Union Flag also appears in the canton (upper left-hand quarter) of the flags of several nations and territories that are former British possessions or dominions.
