What is the difference between sliding and slipping?
Advertisements
उत्तर
Sliding:
- The velocity of the center of mass is greater than Rω i.e. VCM > Rω.
- The velocity of translational motion is greater than the velocity of rotational motion.
- Resultant velocity acts in the forward direction.
Slipping:
- The velocity of the center of mass is lesser than Rω. i.e. VCM < Rω
- The velocity of translation motion is lesser than the velocity of rotational motion.
- Resultant velocity acts in the backward direction.
