Plane of rotation

A plane of rotation is like a sheet of paper that a toy spins on. Imagine you have a toy car and you put it on a piece of paper. If you spin the toy car around on the paper, it's moving on a plane of rotation.

Now, let's imagine you have a real car instead of a toy car. If you want to spin the car around, you need to pick it up and turn it around. But when you pick up the car, you're not just moving it around a sheet of paper anymore. You're moving it through the air, which makes it harder to spin.

So, a plane of rotation is a flat surface that makes it easier to spin things. It's like a special playing field where toys and other objects can spin around without getting caught in the air. It's a special kind of surface that helps make things spin!
