Rolling without Slipping ConditionMediumQuestion 30330
Question
A ball rolls without slipping on a rough surface. The friction acting on it is:
- AKinetic friction forward
- BStatic friction forwardCorrect
- CZero
- DStatic friction backward
Correct answer
Static friction forward
Explanation
For a ball rolling and being decelerated on a rough surface, static friction acts forward at the contact point (opposing the tendency for the contact point to slide backward). This is the key feature of rolling motion.
