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:
The Cataracs was an American hip hop indie-pop production project (formerly duo) formed in Berkeley, California consisting of songwriter, vocalist, and producer Niles "Cyranizzy" Hollowell-Dhar (born 6 October 1988), and formerly songwriter and vocalist David "Campa" Benjamin Singer-Vine (born 1987). The duo started out as an independent group, during their years at Berkeley High School. The two were first signed to the label Indie-Pop. Singer-Vine left the group in August 2012 with Hollowell-Dhar continuing on with the name The Cataracs despite David's departure. Hollowell-Dhar also released materials starting 2014, under the name of KSHMR.
The duo met in their sophomore year while attending Berkeley High School. Singer-Vine was featured in a rap CD that was being passed around campus. When Dhar eventually heard the CD, he subsequently created a response. However, the “diss” response brought the two together and they soon became friends. In 2003, the two joined together to create what is now The Cataracs (named after the phrase “Who smoke ‘til your eyes get cataracts” from Snoop Dogg's song “What's my name Pt. 2”). In the summer of 2006, they released their first album, Technohop Vol. 1. In August 2006, the group joined with The Pack to make the single “Blueberry Afghani”. The song soon became a hit and was chosen as a “Download of the Week” by 106 KMEL and many music sites such as The Fader, UK’s Hip Hop Connection and XLR8R praised it.
Sunrise is a side-platformed Sacramento RT light rail station in Rancho Cordova, California, United States. The station was opened on June 11, 2004, and is operated by the Sacramento Regional Transit District. As part of the Gold Line, it has service to Downtown Sacramento, California State University, Sacramento, Gold River and Folsom. The station is located on Folsom Boulevard just south of Highway 50 at the intersection of Sunrise Boulevard.
Sunrise, along with Zinfandel and Cordova Town Center, opened on June 11, 2004, as part of an $89 million, 2.8-mile (4.5 km) extension of the Gold Line east of the Mather Field/Mills station. Sunrise served as the eastern terminus for the Gold Line until the extension to Historic Folsom opened on October 15, 2005. Rancho Cordova city officials have stated the establishment of the stations will help in the development of transit-oriented development/redevelopment of the Folsom corridor through the city.
Sunrise serves as a major station on the eastern section of the Gold Line. Light rail operates from this stop to downtown at 15-minute intervals during peak time periods, while trains leave Folsom at 30-minute headways during this portion of the day. Many trains end their routes at this facility, as service between Folsom and Sunrise ceases as 7:30 p.m. every evening. Additionally, connection to RT Bus Route 74 can be made, and there is a 487-space park and ride lot located at the station.
Sunrise is a 1926 Australian silent film co-directed by Raymond Longford, who took over during filming. It was the second film from Australasian Films following their recommencement of production, after Painted Daughters.
It is considered a lost film.
George Willis loses his unfaithful wife in a rock fall and takes to the bush He rescues a girl, Hope Stuart, from a flood and nurses her back to health. When he brings her back to her father he discovers that an old enemy, Arthur Greerson, has accused him of murder.
Greerson is injured in a mining accident and after George rescues him, Greerson admits he has lied. George returns to his life as a recluse in the mountains, followed by Hope.
The film was shot on location in the Blue Mountains at Bargo with interiors at the studios of Australasian Films in Bondi. F. Stuart Whyte began directing but left Australia during shooting for unknown reasons. He was replaced by Longford, who had recently contracted to Australasian Films.
