What is emission-based?

Emission-based means something depends on how much stuff is let out or given off.

Imagine you're playing with a toy car that moves by blowing air through it, like a mini fan. The more air you blow, the faster the car goes. That’s emission-based: the amount of air (or emission) you put in affects how much the car moves.

Think of your breath as the air. If you blow gently, the car moves slowly. If you blow hard, it zooms off! The more stuff (like air or sound) is let out, the bigger the effect, just like when you shout in a tunnel and the echo gets louder.

Emission-based systems are everywhere. Like a loudspeaker: the louder your voice, the louder the speaker makes it. Or even a fire: the more wood you burn, the hotter the fire gets. It's all about how much stuff is being let out, and that tells us how strong or big something will be.

So next time you blow on a toy car, remember: you're using an emission-based system!
