glidnings

Glidnings is a Swedish term that refers to sliding or gliding motion. It appears in a range of disciplines and is often found in compounds such as glidningskoefficient (coefficient of sliding friction), glidningsförlopp (gliding process), or glidningsytor (sliding surfaces). The core idea is the relative movement of one body with respect to another, typically involving contact and friction.

In physics and engineering, glidning describes the motion where surfaces slide past each other. This is distinct from rolling motion and is associated with kinetic friction and wear between contacting surfaces. The concept is central to tribology, lubrication, and mechanical design, where the goal is to understand and control sliding forces, friction coefficients, and wear rates.

In aviation and transportation, glidning is commonly used to denote gliding flight, a mode of flight without engine power. An aircraft converts potential energy into forward motion and lift to maintain altitude, gradually descending along a glide path. Gliding efficiency is characterized by the glide ratio, which describes how far the aircraft travels horizontally for a given loss of altitude.

In everyday language and biomechanics, glidning can describe sliding motions in joints or between surfaces, as well as simple sliding movement observed in sports, skiing, or skating. Because glidnings covers a broad concept, its precise meaning depends on context, with specialized terms guiding interpretation in physics, engineering, aviation, or biomedicine.
