Free fall
In Newtonian physics, free fall is any motion of a body where gravity is the only force acting upon it. In the context of general relativity, where gravitation is reduced to a space-time curvature, a body in free fall has no force acting on it and moves along a geodesic. The present article only concerns itself with free fall in the Newtonian domain.
An object in the technical sense of free fall may not necessarily be falling down in the usual sense of the term. An object moving upwards would not normally be considered to be falling, but if it is subject to the force of gravity only, it is said to be in free fall. The moon is thus in free fall.
In a uniform gravitational field, in the absence of any other forces, gravitation acts on each part of the body equally and this is weightlessness, a condition that also occurs when the gravitational field is zero (such as when far away from any gravitating body). A body in free fall experiences "0 g".
The term "free fall" is often used more loosely than in the strict sense defined above. Thus, falling through an atmosphere without a deployed parachute, or lifting device, is also often referred to as free fall. The aerodynamic drag forces in such situations prevent them from producing full weightlessness, and thus a skydiver's "free fall" after reaching terminal velocity produces the sensation of the body's weight being supported on a cushion of air.
Charles "Nish" Bruce
Sergeant Charles Christian Cameron "Nish" Bruce QGM (8 August 1956 – 8 January 2002) was a former British Army soldier and freefall expert of high altitude military parachuting who served in 22 (SAS) Special Air Service (1982–88). He served with the 22 SAS in the Falklands War, on anti-drug operations in South and Central America and in Northern Ireland during Operation Banner for which he was awarded the Queen's Gallantry Medal in 1986.
He received the South Atlantic Medal in 1982 with B Squadron of the 22 Special Air Service and the General Service Medal with the 2nd Battalion, Parachute Regiment for services in Northern Ireland during The Troubles.
Family & Early Life
Bruce was born in Chipping Norton in 1956, middle son of Ewen Anthony Guy Cameron Bruce. He was the paternal grandson of Major Ewen Cameron Bruce (of Blaen-y-cwm).
Military career
Bruce joined the Parachute Regiment in 1973 at age 17 and in 1978 spent 4 years with The Red Devils Display Team participating in test jumping, international exhibitions and competitions before passing SAS selection and joining 22 SAS in April 1982.
Free fall (disambiguation)
Free fall is the ability to achieve the sensation of weightlessness (for example to be falling freely in an atmosphere, or to be in zero-g). In skydiving, the term freefall is also used for the portion of the skydive prior to the deployment of a parachute, even though significant portions of it are at terminal velocity rather than freely accelerating in gravity.
Free fall, Free-fall or Freefall may also refer to:
Books & comics
Evolution (Baxter novel)
Evolution is a collection of short stories that work together to form an episodic science fiction novel by author Stephen Baxter. It follows 565 million years of human evolution, from shrewlike mammals 65 million years in the past to the ultimate fate of humanity (and its descendants, both biological and non-biological) 500 million years in the future.
Plot summary
The book follows the evolution of mankind as it shapes surviving Purgatorius into tree dwellers, remoulds a group that drifts from Africa to a (then much closer) New World on a raft formed out of debris, and confronting others with a terrible dead end as ice clamps down on Antarctica.
Evolution (Nektar album)
Evolution is the tenth album by progressive rock band Nektar, released in 2004. It was the first Nektar album since 1977's Magic Is a Child to feature original drummer Ron Howden, who rejoined other founding members Roye Albrighton and Taff Freeman.

Evolution (Korn song)
"Evolution" is a song by American nu metal band Korn. The song was the first single to be released from the band's untitled album on June 12, 2007. It is one of the four tracks in which Brooks Wackerman of Bad Religion performed drumming duties.
Promotion
Music video
"Evolution", directed by Dave Meyers, was filmed on June 15, 2007 in Los Angeles. The music video features Slipknot drummer Joey Jordison. According to the casting call sheet, "Evolution" is "filled with political satire and humor." The production team sought mostly male actors to fill roles such as "hero scientists", religious politicians, doctors, green peace guys, anthropologists, military men, and "government types". Casting interviews were held June 12 and 13, 2007.
Viral marketing
The domain www.evolutiondevolution.com was set up in promotion of the song. The website is a spoof to promote the "Evolution" music video. It is themed as a documentary publication website and features Korn acting as "experts" who studied evolution in support of a fake documentary titled Devolution: Nature's U-Turn. Vocalist Jonathan Davis explained that the band wanted to try a different kind of promotion, and so created the website and several viral promotion trailers.
