Smoothness

Smoothness refers to how gradually and evenly a surface, curve, or change occurs without abrupt jumps or roughness. In practical terms, a smooth surface feels even and soft to touch, while a smooth curve in a graph indicates steady, predictable progress without sudden spikes or dips. It reflects consistency and harmony in the shape or function, making things easier to interpret, predict, or navigate. Smoothness is important in various fields, including manufacturing, design, and data analysis, because it signifies quality, stability, and seamless transitions.
