Explanation:

Friction is the force that resists the relative motion of solid surfaces, fluid layers, and material elements sliding against each other. When two surfaces are moving against each other, the frictional force acting between them is called kinetic friction. Kinetic friction is a type of friction that occurs when there is relative motion between the two surfaces.

Kinetic friction.
