  1. Friction

    Friction is the force caused by, and 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 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. ⁕Lubricated friction is a case of fluid friction where a fluid separates two solid surfaces. ⁕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. When surfaces in contact move relative to each other, the friction between the two surfaces converts kinetic energy into heat. This property can have dramatic consequences, as illustrated by the use of friction created by rubbing pieces of wood together to start a fire. Kinetic energy is converted to heat whenever motion with friction occurs, for example when a viscous fluid is stirred. Another important consequence of many types of friction can be wear, which may lead to performance degradation and/or damage to components. Friction is a component of the science of tribology.

  1. Friction

    Surface resistance to the relative motion of one body against the rubbing, sliding, rolling, or flowing of another with which it is in contact.
