Ball bearings are used to convert static friction intoa)rolling fricti...
The correct option is rolling friction.
Ball Bearings:
- A device known as a ball-bearing is made up of two rings and two freely moving metal balls.
- It is intended to prevent sliding by forcing a machine's moving elements to roll over one another.
- The static friction is changed into rolling friction by them.

Ball Bearings and Friction:
Ball bearings are mechanical components used to reduce friction between moving parts. They are designed to convert static friction into rolling friction, which helps in smoother movement and efficiency in various applications.
Static Friction:
- Static friction is the force that resists the initial motion of an object at rest.
- When two surfaces are in contact and not moving relative to each other, static friction comes into play.
Rolling Friction:
- Rolling friction is the resistance encountered when one object rolls over another.
- Ball bearings are specifically designed to reduce rolling friction by using small metal balls to allow smooth rotation between two surfaces.
Importance of Ball Bearings:
- By converting static friction into rolling friction, ball bearings help in reducing wear and tear on components.
- They also help in improving the efficiency and performance of machines by minimizing the energy lost to friction.
In conclusion, ball bearings play a crucial role in converting static friction into rolling friction, which is essential for smooth movement and optimal performance in various mechanical systems.
