Webtive of r(t), we get precisely what we would want from such a derivative: the vector r′(t) points in the direction of travel of the object and its length tells us the speed of travel. In the case that t is time, then, we call v(t) = r′(t) the velocity vector. Even if t is not time, r′(t) is useful—it is a vector tangent to the curve.
