    Etymology: From friction and directly from frictionem, nom. frictio


  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.

Chambers 20th Century Dictionary

  1. Friction

    frik′shun, n. the act of rubbing: (statics) a force acting in the tangent plane of two bodies, when one slides or rolls upon another, and always in a direction opposite to that in which the moving body tends: difficulty, unpleasantness.—adjs. Fric′ative, produced by friction, used of those consonants which are produced by the breath being forced through a narrow opening; Fric′tional, relating to, moved by, or produced by friction.—n. Fric′tion-gear′ing, a method of imparting the motion of one wheel or pulley to another by mere contact.—adj. Fric′tionless, having no friction.—n.pl. Fric′tion-wheels, wheels that lessen friction. [Fr.,—L. frictionemfricāre, frictum, to rub.]

U.S. National Library of Medicine

  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.
