The correct answer is actually **d) Sliding friction**, not **a) Rolling friction**.
Ball bearings are used to reduce **sliding friction** between two surfaces by replacing it with **rolling friction**. In a machine, when parts move relative to each other, sliding friction can create significant resistance and wear. By using ball bearings, which facilitate rolling motion, the friction between the moving parts is significantly reduced. This is because rolling friction, which occurs in ball bearings, is generally lower than sliding friction. Thus, ball bearings help to decrease the resistance and wear associated with sliding motion.

Ball bearings replacing sliding friction in machines
Ball bearings are used in machines to replace sliding friction, which is the resistance encountered when two surfaces slide against each other. This type of friction can lead to a lot of wear and tear on the machine parts, reducing efficiency and increasing the need for maintenance.
Rolling friction
Instead of sliding against each other, ball bearings use rolling friction. This means that the balls within the bearing roll smoothly against the inner and outer races of the bearing, reducing the amount of friction generated. This rolling motion allows for smoother operation of the machine, reducing energy loss and wear on the parts.
Reduction in friction
By replacing sliding friction with rolling friction, ball bearings help to reduce the amount of energy needed to operate a machine. This can lead to increased efficiency, reduced heat generation, and longer lifespan of the machine parts. Additionally, ball bearings can help to absorb shock and vibration, further protecting the machine components.
Applications of ball bearings
Ball bearings are used in a wide range of machines and equipment, including automobiles, industrial machinery, household appliances, and more. They play a crucial role in ensuring smooth and efficient operation of these devices by reducing friction and wear on moving parts.
In conclusion, ball bearings are essential components in machines as they replace sliding friction with rolling friction. This helps to improve efficiency, reduce wear and tear, and prolong the lifespan of various mechanical systems.
