Final answer:
Kinetic friction is the term used to describe the friction between two surfaces that rub against each other when they are in motion.
Step-by-step explanation:
Friction between two surfaces that are in contact and moving relative to one another is called kinetic friction. When two surfaces rub against each other, the roughness of the surfaces and the adhesive forces between the molecules of the objects contribute to the frictional force.
The dependency of friction on the nature of the substances is demonstrated by the fact that rubber-soled shoes slip less than those with leather soles.
