Amateur rocket motor classification

Okay, imagine you're playing with toy cars. Some are little and slow, and some are big and fast. Rocket motors are kind of like toy cars, except they make rockets go really high up in the sky!

But just like real cars, we need to make sure the rocket motors are safe and don't hurt anyone. That's where classification comes in. It's like sorting the cars into different groups based on how powerful they are.

There are different letters and numbers that tell us which group the rocket motor belongs to. The letters usually stand for the type of fuel the motor uses. For example, an "A" motor uses black powder and is the smallest and least powerful kind. A "B" motor uses a bit more fuel and is medium-level. And a "C" motor is even bigger and stronger than a "B."

The numbers after the letter tell us how strong the motor is. For example, an "A3" motor is weaker than an "A5" motor. This is important because we want to make sure we use the right kind of motor for the size of the rocket we're building.

Overall, rocket motor classification is a way to keep us safe and help us choose the right motors for our rockets. It's like sorting our toy cars into different groups so we know which ones to play with for different games.
