A water wheel is a mechanical device that harnesses the power of flowing water to perform work, typically through converting the rotational motion of the water into mechanical energy. It consists of a circular frame with buckets or paddles attached to its circumference, which scoop up water and release it on the other side, causing the wheel to turn. This ancient invention has been used for centuries in various applications such as grinding grain, pumping water, and powering machinery.
