Question

what is the difference between static friction, rolling friction and sliding friction? for a pair of objects which of the three is greater?

Answer 1

The static friction is in most cases higher than the kinetic friction. Rolling friction is the frictional force that occurs when one object rolls on another, like a car's wheels on the ground. ... Sliding friction is when two solid surfaces slide against each other.For a given pair of objects static friction is most of the time greater than sliding or kinetic friction due to the amount of the force used to overcome it.
