And at two seconds, our velocity becomes positive. And that makes sense, because at two seconds was when our velocity switched directions to the rightward direction. So our velocity is getting more and more negative, less and less negative, and then we switch directions, and we go just like that. And we see it right over here. Now, one thing to keep in mind when we're thinking about velocity as a function of time is that velocity and speed are two different things. Speed, speed, let me write it over here. Speed is equal to, if you're thinking about it in one dimension, you could think about it as the absolute value of your velocity as a function of time, or your magnitude of velocity as a function of time.
