Now this is interesting, this last point. Because you might be tempted to say, all right, I'm oscillating, I'm going up, then I'm going down, then I'm going back up. Maybe I'm moving forward here. But remember, what we're thinking about here, this isn't position versus time, this is velocity versus time. So if our velocity is negative, we're moving backwards. And here, our velocity is still negative. It's becoming less negative, but it's still negative.
