What is the origin of the idiom "crack the whip" and when to use it?

The origin of the idiom "crack the whip" likely stems from the practice of using a whip as a tool of control or dominance.

The action of cracking the whip produces a loud sound, which serves as an auditory cue to command or guide the animals.
