Good Night and Sweet dreams dear mate...........⚘✨

Explanation:

⭐Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other. There are several types of friction:

⭐Dry friction is a force that opposes the relative lateral motion of two solid surfaces in contact. Dry friction is subdivided into static friction ("stiction") between non-moving surfaces, and kinetic friction between moving surfaces. With the exception of atomic or molecular friction, dry friction generally arises from the interaction of surface features, known as asperities

⭐Fluid friction describes the friction between layers of a viscous fluid that are moving relative to each other.

Lubricated friction is a case of fluid friction where a lubricant fluid separates two solid surfaces.

Skin friction is a component of drag, the force resisting the motion of a fluid across the surface of a body.

⭐Internal friction is the force resisting motion between the elements making up a solid material while it undergoes deformation.
