Think about this, the land 10 feet from the north pole only needs to travel like 60 feet when the earth does a full rotation… The land at the equator travels something like 28000 miles in that rotation. All part of the same mass, but one circular slice of the earth is small, one is big… All part of one solid thing, but traveling at different speeds. Not the exact same principle, but hope that gets you in the right thought process.

So let’s say you have something rotating a big gear at 1 rotation per minute, that gear has 100 teeth on it. It’s connected to a gear that’s 1/4 the size, so it has 25 teeth. Every one turn of the 100 teeth on the big gear is going to turn the smaller gear with 25 teeth 4 times, so whatever it’s spinning is going to be four times faster than what’s spinning the big gear
