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:
When surfaces in contact move relative to each other, the friction between the two surfaces converts kinetic energy into thermal energy (that is, it converts work to 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 thermal energy 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.
Friction, the third and final album (until 2013) by Coney Hatch, was released in 1985. Drummer Dave Ketchum left prior to this release, to be replaced by Barry Connors, formerly of Toronto.
Friction (フリクション furikushon) is an influential rock band from Japan, formed in 1978. They originally began in 1971 under the name Circle Triangle Square, and are considered to be one of the pioneers of Japan's alternative rock scene. In September 2007, Rolling Stone Japan rated their debut album Atsureki at #21 on its list of the "100 Greatest Japanese Rock Albums of All Time".
Originally formed in 1971 as an avant-garde music group by bassist Reck, saxophonist Chico Hige, and drummer Sakuro Watanabe in Tokyo, Japan. They changed the band's name to 3/3 in the mid 70s, and Reck and Chico later moved to the United States, where they would form the band Teenage Jesus and the Jerks with Lydia Lunch and James Chance, and later became the original founding members of James Chance and the Contortions before returning to Japan.
Renaming 3/3 to form Friction, they recruited guitarist Tsunematsu Masatoshi, who had studied art at the Tokyo National University of Fine Arts & Music. They released a live album and single in 1979, and their first studio album, Atsureki (軋轢, meaning 'friction' in Japanese) in 1980, produced by Ryuichi Sakamoto. Tsunematsu left the band in December 1980 to become an artist, and from then on Friction has had numerous guest instrumentalists for lives and studio releases, all revolving around frontman Reck. The live video titled Dumb Numb was directed by Sogo Ishii. Towards the year 2000, Friction went on hiatus when Reck started producing for other musicians, but restarted in 2007.
Driftwood is wood that has been washed onto a shore or beach of a sea, lake, or river by the action of winds, tides or waves. It is a form of marine debris or tidewrack.
In some waterfront areas, driftwood is a major nuisance. However, the driftwood provides shelter and food for birds, fish and other aquatic species as it floats in the ocean. Gribbles, shipworms and bacteria decompose the wood and gradually turn it into nutrients that are reintroduced to the food web. Sometimes, the partially decomposed wood washes ashore, where it also shelters birds, plants, and other species. Driftwood can become the foundation for sand dunes.
Most driftwood is the remains of trees, in whole or part, that have been washed into the ocean, due to flooding, high winds, or other natural occurrences, or as the result of logging. There is also a subset of driftwood known as drift lumber. Drift lumber includes the remains of man-made wooden objects, such as, buildings and their contents washed into the sea during storms, wooden objects discarded into the water from shore, dropped dunnage or lost cargo from ships (jetsam), and the remains of shipwrecked wooden ships and boats (flotsam). Erosion and wave action may make it difficult or impossible to determine the origin of a particular piece of driftwood.
Driftwood is a 1947 drama film directed by Allan Dwan and starring Natalie Wood as a little orphan girl who adopts a collie. The movie also stars Ruth Warrick, Walter Brennan, Dean Jagger and Charlotte Greenwood.
Driftwood is wood that has been deposited on land by the action of waves.
