👉 Curviness is a measurement of how much a curve, such as a line or a surface, deviates from its straight path. It can be calculated by measuring the curvature at various points on the curve and dividing that value by the radius of curvature (the distance from the center of the curve to any point). Curviness is often used in engineering and physics to describe how smooth a surface is and to help understand how different materials behave under pressure or strain.
