Physics help

I'm doing a project in my physics class about freefall. I'm stuck on this one question about terminal velocity. It asks, when a skydiver reaches terminal velocity, why do they keep falling? I think it has something to do with the initial acceleration or perhaps Newton's first law of motion but I'm not entirely sure.

Don't take anything I say seriously, because what I say may not necessarily be what I mean.

Terminal velocity is actually very simple: it's the constant final speed reached when the fore of gravity and drag are in balance. In short, gravity can't make the object go faster, nor can drag slow it down more: the acceleration is thus exactly 0, but the speed is not.

Terminal velocity is the speed the guy is going when he hits the ground.
Sorry about the smartass answer but the question was over my head.
