O The disk rolls and the sliding is impending. O The disk rotates and slides. The disk rolls without sliding. The disk neither rotates nor slides.

When analyzing the motion of a disk or wheel rolling on a plane surface, one common assumption is that the disk rolls without sliding. This means that every point of contact between the disk and the surface moves without slipping, ensuring that the relationship between translational and rotational motion adheres to the rolling condition. This simplifies calculations and provides a clear understanding of the dynamics involved. In real-world applications, this assumption is vital for scenarios like vehicles on a road or machinery where wheels play a key role. If the wheels were to slide, it would lead to less friction, causing wear and tear on both the wheel and the surface, not to mention affecting control and stability. Understanding rolling motion versus sliding motion helps enhance the design and functionality of everyday transportation and mechanical systems.
