Detailed explanation-1: -When two solid surfaces slide over each other, a frictional force is produced between them, known as kinetic friction also referred to as sliding friction. It is the sliding friction that facilitates us in walking as it is the relationship between gravity, mass and the friction.

Detailed explanation-2: -Sliding friction-when two solid surfaces slide over each other. 4. Rolling friction-when an object rolls across a surface.

Detailed explanation-3: -Static, sliding, and rolling friction occur between solid surfaces. Static friction is strongest, followed by sliding friction, and then rolling friction, which is weakest.
