ELI5: When cooking popcorn, how do the fist kernels that pop not burn before the rest of the bag finishes popping; yet, overcook it just a bit and ALL of the popped kernals are burnt?

The popping of the kernels is basically stirring the popcorn but when that slows down enough, the popcorn on the bottom burns, but not all of it. If it's burned badly enough, the smoke will make it all taste burned.
The same burning will happen if you try to pop too much popcorn for your container and being too full makes the popcorn cram in place, and then the bottom burns.
