The function of the ball bearing in the wheel is

The function of the ball bearing in the wheel is to convert static friction into kinetic friction, as described by option [C]. When a wheel initially starts moving, static friction can impede its motion. Ball bearings reduce this resistance, enabling smoother rotation by facilitating the transition from static to kinetic friction. This conversion allows the wheel to move more freely, reducing wear and tear on both the wheel and its axle. By enabling smoother rotation, ball bearings also contribute to energy efficiency and enhance the overall performance of mechanical systems. While they do provide convenience by facilitating smooth motion, their primary function is to reduce frictional resistance and improve the efficiency of rotating mechanisms. Thus, ball bearings play a crucial role in various applications, from automotive and industrial machinery to household appliances, where smooth and efficient motion is essential for optimal performance.
