Governor

A governor is like a big helper that makes sure things are going at the right speed. Think of it like when you're riding a bike and your grown-up tells you to go slow or fast so you don't fall over.

In machines like cars or engines, the governor works by telling the engine to go slower or faster by controlling how much fuel or air goes into the engine.

It's important because if the engine goes too fast or too slow, it can get damaged or stop working completely. The governor makes sure everything stays just right, like Goldilocks would say - not too fast, not too slow, but just right!
