Answer:
(a) Sliding friction is greater than rolling friction.
(b) Static friction is greater than sliding friction.
(c) Frictional force due to rough surfaces is more than the friction due to smooth surfaces.
Explanation:
(A) Rolling friction:
- It is the friction developed when the body is in rotational motion.
- It is developed between the surface and the point of contact of the body.
- It is the weakest frictional force among all the frictional forces.
(B) Sliding friction:
- The friction accumulated when the body is performing the translation motion.
- It is developed between the surface and the point of contact of the body.
- The sliding friction is more than the rolling friction but less than the static friction.
(C) Static friction:
- The friction is present between the surface and the body when the body is at rest.
- Static friction is the greatest among all the types of frictional forces.
(a) Sliding friction is greater than rolling friction.
(b) Static friction is greater than sliding friction.
(c) Frictional force due to rough surfaces is more than the friction due to smooth surfaces.
