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 resists 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.
  • Fluid friction describes the friction between layers within a viscous fluid that are moving relative to each other. [1] [2]
  • Lubricated friction is a case of fluid friction where a fluid separates two solid surfaces. [3] [4] [5]
  • Skin friction is a component of drag, the force resisting the motion of a solid body through a fluid.
  • Internal friction is the force resisting motion between the elements making up a solid material while it undergoes deformation.

if friction isnt there then following activities wont occur

  • Friction between meteorite and air helps to increase its temperature and ignite it, protecting the living things on Earth.
  • Finger prints and palm prints on hand help to hold up objects easily in human and ape hands.
  • Foot prints increase friction and helps to stand up.
  • Automobile brakes inherently rely on friction, slowing a vehicle by converting its kinetic energy into heat. Incidentally, dispersing this large amount of heat safely is one technical challenge in designing brake systems.
