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:

When he was 15, he won a swimming competition and broke his leg, resulting in the alias "Plastered Leg". Zhao Shen Shen ditched school one day with her next-door neighbor, Zuo Jun, and got into a bus accident. She has been mute ever since. One day, on her way to the hospital, Shen Shen's mom gets hit by a car and doesn't survive. Wei Yi and Shen Shen both feel lonely so they send and receive messages at an abandoned bomb shelter. After a while, they meet each other and start communicating. Wei Yi does not know about Shen Shen's accident which caused her to be mute; he just thinks that Shen Shen does not like to speak.

The series was initially promoted as a trilogy, with later announcements stating that the series would comprise four books.
Film rights to the series have been purchased by LD Entertainment and book rights have been sold in 13 countries.
Nora Grey meets Patch Cipriano in her biology class. She finds herself drawn to him despite him initially trying to assassinate her and her friends preferring that she date their friend Elliot, who is later revealed to be a pawn of the Nephilim Jules. Patch saves Nora from death multiple times because he realizes he has fallen in love with her. Even though Nora believes he is stalking her, she eventually gives in to her feelings for Patch after he reveals he is a fallen angel who is protecting her. Jules, also known by the name Chauncey Langeais, attempts to use Nora as a way to target Patch, but fails and is killed when Nora jumps off of a gym ceiling rafter and dies, severing the blood-related tie between Nora and him. She is brought back by Patch, who then becomes her guardian angel.
