What is "free fall"

n. A variant form of '''freefall'''.

1. n. the ideal falling motion of something subject only to a gravitational field

2. a sudden sharp decrease in some quantity; "a drop of 57 points on the Dow Jones index"; "there was a drop in pressure in the pulmonary artery"; "a dip in prices"; "when that became known the price of their stock went into free fall" [syn: drop, dip, 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.

Free Fall is a studio album by the jazz fusion band Dixie Dregs, released in 1977. The band's second album (following 1976's self-released The Great Spectacular), it was their first release on the Capricorn Records label.

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:

Free Fall is the fourth novel of English novelist William Golding, first published in 1959. Written in the first person, it is a self-examination by an English painter, Samuel Mountjoy, held in a German POW camp during World War Two.

Free Fall is an album by Jimmy Giuffre, released in 1963.

Free Fall is a 1999 American/ Canadian made-for-television action / drama film directed by Mario Azzopardi, based on a story by Mark Homer, and screenplay by Ken Wheat and Jim Wheat. The film stars Jaclyn Smith, Bruce Boxleitner, Scott Wentworth, Hannes Jaenicke and Hayden Christensen. The film documents an unusual series of crashes that involves sabotaged airliners.

Free Fall is the first full-length studio album by Swedish heavy metal songwriter, guitarist, multi-instrumentalist and producer Magnus Karlsson.

It was released under the project name Magnus Karlsson's Free Fall on June 11 2013 in North America and June 14 in Europe by Frontiers Records and features many guest singers who worked with Magnus on his many previous projects, including Russell Allen (one of the singers of the duo Allen/Lande), Ralf Scheepers (vocalist of Primal Fear, Magnus current band), Tony Harnell (who worked with Magnus in the band Starbreaker), Rickard Bengtsson (former bandmate from Last Tribe), Mark Boals (who worked with Magnus in the project The Codex), Mike Andersson (who worked with Magnus in the project Planet Alliance) and some other famous friends like David Readman ( Pink Cream 69, Voodoo Circle), Rick Altzi ( At Vance, Masterplan) and Herman Saming ( A.C.T).

Magnus also sings three tracks on the album himself and Daniel Flores (who also worked with Magnus in the project The Codex) recorded the drums.

Free Fall is a 2013 German drama film directed by Stephan Lacant who also wrote the script with Karsten Dahlem, and starring Hanno Koffler, Max Riemelt, and Katharina Schüttler. The film tells the story of police officer, Marc Borgmann (Koffler), who lives with his pregnant girlfriend, Bettina Bischoff (Schüttler). Whilst on a training course, Borgmann meets fellow police officer, Kay Engel (Riemelt), and a romance develops between the two men. Borgmann is torn between his love for Bettina and his new found feelings for another man. When Engel disappears for a while, Borgmann realises his life is rapidly going into " free fall", as he cannot meet the high expectations of the people he knows.

Filming began in Ludwigsburg, Germany, in the summer of 2012. Freier Fall has been compared to Brokeback Mountain and received good reviews following its première at the Berlin Film Festival on 8 February 2013, and at the Frameline Film Festival in the United States on 21 June 2013. The original motion picture soundtrack written by music duo Dürbeck & Dohmen was released digitally online by MovieScore Media to coincide with the film's opening release on 23 May 2013. It made a box office gross of $599,721.

A sequel, Free Fall 2 ( German: Freier Fall 2), has been announced.

"Free Fall" is the twentieth episode of the fourth season of Pretty Little Liars, an American mystery drama television series based on the novel series written by Sara Shepard, and is the ninety-first episode of the series. The episode, directed by Melanie Mayron and written by Maya Goldsmith, originally aired on February 18, 2014 on ABC Family.

In the episode, Spencer is ready to tell Aria that Ezra is "A", while Hanna and Emily, worried that Aria will be hurt, remain hesitant. Meanwhile, Spencer’s addiction to amphetamines is exposed, causing damage to her credibility among the Liars.

“Free Fall” yielded 2.56 million viewers and a 1.0 demo rating, up from the previous episode. It received general praise from contemporary critics, who highlighted the dialogue between Ashley Benson and Shay Mitchell’s characters and drew comparisons to Rosencrantz and Guildenstern.
