one of the meanings of "swing" from oxfordlearnersdictionaries.com:
to swing - to move or make something move with a wide curved movement:
(1) A line of cars swung out of the palace gates.
I understand "swung" means some movement here.
But I can't understand what specific movement it means.
What is "a wide curved movement" as applied to (1)?
To better understand (1), I will introduce my variant with "moved":
(2) A line of cars moved out of the palace gates.
What is the difference between (1) and (2)?
