When a finger is placed in the center of a fan, it experiences a larger circular motion due to the movement of the fan blades around it. The center of the fan is a fixed point, while the blades are in motion, creating a larger radius for the finger's tip. Friction can cause the finger to shift slightly from the exact center, contributing to the circular motion observed. Pressing the finger firmly against the center minimizes movement, demonstrating the relationship between the fan's rotation and the position of the finger. Understanding this concept highlights the dynamics of rotational motion in fans.
