c. rolling friction
d. limiting friction
Text Solution
Verified by Experts
(a) Static friction : The frictional force applied by the surface when the body is at rest is called static friction. (b) Dynamic friction : The frictional force applied by the surface when the body is in motion is called dynamic friction. (c ) Rolling friction : The frictional force applied by the surface when the body is in rolling motion is called rolling friction. (d) Limiting friction : the maximum static friction is called limiting friction.
