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.
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.
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).
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 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:
A storm is any disturbed state of an environment or astronomical body's atmosphere especially affecting its surface, and strongly implying severe weather. It may be marked by significant disruptions to normal conditions such as strong wind, hail, thunder and lightning (a thunderstorm), heavy precipitation (snowstorm, rainstorm), heavy freezing rain (ice storm), strong winds (tropical cyclone, windstorm), or wind transporting some substance through the atmosphere as in a dust storm, blizzard, sandstorm, etc.
Storms generally lead to negative impacts on lives and property such as storm surge, heavy rain or snow (causing flooding or road impassibility), lightning, wildfires, and vertical wind shear; however, systems with significant rainfall can alleviate drought in places they move through. Heavy snowfall can allow special recreational activities to take place which would not be possible otherwise, such as skiing and snowmobiling.
The English word comes from Proto-Germanic *sturmaz meaning "noise, tumult".
Storm is a Malagasy power metal band formed in 1998. They are one of the few Madagascar-based bands to play heavy metal and the first to play power metal. All of their lyrics are written in the Malagasy language. They released their self-titled debut album in 2005.
Storm (2005)
Storm is a 2005 Swedish fantasy-thriller film directed by Måns Mårlind and Björn Stein. The film stars Eric Ericson, Eva Röse and Jonas Karlsson. The official opening of Storm was on 20 January 2006, but the actual opening was at a preview of the film on 18 November 2005 during the Stockholm Film Festival, where it also was awarded. Before 2006, Storm had already been sold to 18 other countries.
Slacker Donny's (Eric Ericson) life is turned upside-down when Lova (Eva Rose) enters his life possessing a mysterious box which may hold answers to eternal and dangerous questions. But evil forces want to possess the box, and Donny and Eva must travel through time to ensure the future of mankind.
The film was shot in Stockholm, Vänersborg (as the abandoned city) and in Trollhättan, a.k.a. Trollywood.
Steve Pattee from "horrortalk.com" blamed the film for having a "less than satisfactory" ending, but he gave three out of five stars. A blogger named Cyrus also spoke of a "less than satisfying ending" because there was possibly "a bit too much" left for the viewer to ponder. Bill Gribon from "dvdtalk.com" appreciated "Storm" as "fascinating food for thought".
