An important topic related to arc length is curvature. The concept of curvature provides a way to measure how sharply a smooth curve turns. A circle has constant curvature. The smaller the radius of the circle, the greater the curvature. Think of driving down a road. Suppose the road lies on an arc of a large circle.
