What are gyrocompasses?

A gyrocompass is like a super-smart toy that always knows which way is north, no matter how you shake it or turn it around.

Imagine you have a spinning top that never stops spinning, and it's inside a box. This top helps the box figure out where north is. That’s what a gyrocompass does on ships and planes, it helps them know their direction without looking at the sun or stars.

A gyrocompass has a spinning wheel inside it, just like your toy top. When the wheel spins really fast, it wants to keep spinning in the same direction, even if you move the box around. This helps it stay pointed toward north, no matter what.

Unlike a regular compass that uses magnets, a gyrocompass doesn’t care about metal or electricity. It just keeps spinning and pointing north, like your toy top always points in one direction, even if you move it around!
