rolling

Rolling is a mechanical process where a object moves by rotating around its axis or a surface, allowing smooth movement. It typically involves wheels, cylinders, or spheres that turn to transfer motion efficiently, reducing friction compared to sliding. For example, car tires roll on the road, enabling the vehicle to move forward with less effort. Rolling can also refer to techniques in manufacturing, like rolling metal sheets to shape or strengthen them through continuous deformation. Overall, rolling enhances ease and efficiency in movement and manufacturing processes by utilizing rotational motion.
