At the moment, I am reading about fluids and the drag force. There is one particular paragraph that I would like help with, specifically the part in red:
"Here we examine only cases in which air is the fluid, the body is blunt (like
a baseball) rather than slender (like a javelin), and the relative motion is fast
enough so that the air becomes turbulent (breaks up into swirls) behind the body."
Why does the air break up into swirls behind the body?
