Rolling MotionHardQuestion 6148
Question
For rolling without slipping, kinetic friction between body and surface is:
- AKinetic friction acts
- BStatic friction acts (no slipping)Correct
- CNo friction needed
- DRolling friction only
Correct answer
Static friction acts (no slipping)
Explanation
In pure rolling, contact point has zero relative velocity — static friction acts (not kinetic).
