**Step-by-Step Solution:** 1. **Understanding the Question**: The question asks for the type of friction that occurs when one body rolls over another. 2. **Identifying the Motion**: When one object rolls over another, it is important to identify the type of motion involved. In this case, the motion is rolling motion, which is different from sliding motion. 3. **Defining Rolling Motion**: Rolling motion occurs when an object, such as a ball or a wheel, rotates about an axis while moving forward. This means that every point on the rolling object comes into contact with the surface without sliding. ...
