When using three pulleys with a belt where one of them is a small pulley, the small pulley will spin faster compared to the others. This is due to the principle of rotational speed being inversely proportional to the radius of the pulley. The small pulley has a smaller radius, so it will rotate faster than the larger pulleys in the system.
