Interpreting Curvature

For a circle of radius r, the curvature at any point is k = 1/r. One way of interpreting curvature is to think of it as the rate at which the unit tangent vector is changing direction with respect to the arc length parameter. As the radius of the circle increases, the curvature decreases and so does the rate at which the unit tangent vector changes direction.
