For 10 points, name this force that retards motion of an object across a surface with which it is in contact.
This force is necessary for the phenomenon of rolling without slipping; during that motion, this force is sometimes known as traction. The kinetic coefficient of this force is a constant, and is less than the maximum static coefficient, which is proportional to the normal force.
