👉 Unsmoothly is a technical term in physics and engineering that refers to an object or system that has some non-smooth properties. These properties include variations in shape, size, density, or velocity due to its interaction with other objects or the environment. Examples of unsmoothly objects include fluids, gases, and materials that are not perfectly smooth. Unsmoothly objects can be characterized by their high friction coefficients, which indicate that they have a low coefficient of friction between them. This property is often
