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.

Freefall (1994 film)

Freefall is a 1994 action film starring Eric Roberts, Jeff Fahey and Pamela Gidley. It is directed by John Irvin, written and produced by David Zito and Les Weldon.

The story tells about undercover INTERPOL agent Grant Orion (Roberts), who, after recently being falsely accused of a crime, attempts to prove his innocence to wildlife photographer Katy Mazur (Gidley) while rescuing her from an assassin organisation led by her fiancé Dex Dellum (Fahey).

Originally intended for a theatrical release, the movie was released straight to VHS in the United States by Vidmark Entertainment and in Canada that same year by Cineplex Odeon. In 2002, Platinum Disc released a DVD of the film.

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.

Morella, Castellón

Morella is an ancient walled city located on a hill-top in the province of Castellón, Valencian Community, Spain. The town is the capital and administrative centre of the comarca of Els Ports, in the historic Maestrat (Maestrazgo) region.

There are traces of settlement by the Iberians, succeeded by the Greeks and Romans, Visigoths and the Moors. From the early 17th century to the Spanish Civil War, the town was often fought over, due to its strategic situation between the Ebro and the coastal plain of Valencia. Morella is part of the Taula del Sénia free association of municipalities.

Every six years the citizens celebrate the Sexenni, a commemoration of the town's recovery from the plague in the seventeenth century. Tourism now plays an important part in the local economy, along with agriculture. In the 20th century the town and surrounding area became depopulated, a trend that has only been reversed in the early 21st century. The population of Morella in 2008 was 2,854, having declined from a figure of 7,335 in 1900 (INE).

List of craters on Mars: H-N

This is a list of craters on Mars. There are hundreds of thousands of impact crater on Mars, but only some of them have names. This list here only contains named Martian craters starting with the letter H – N (see also lists for A – G and O – Z).

Large Martian craters (greater than 60 km in diameter) are named after famous scientists and science fiction authors; smaller ones (less than 60 km in diameter) get their names from towns on Earth. Craters cannot be named for living people, and small crater names are not intended to be commemorative - that is, a small crater isn't actually named after a specific town on Earth, but rather its name comes at random from a pool of terrestrial place names, with some exceptions made for craters near landing sites. Latitude and longitude are given as planetographic coordinates with west longitude.

Myrica

Myrica /mɪˈraɪkə/ is a genus of about 35–50 species of small trees and shrubs in the family Myricaceae, order Fagales. The genus has a wide distribution, including Africa, Asia, Europe, North America and South America, and missing only from Australia. Some botanists split the genus into two genera on the basis of the catkin and fruit structure, restricting Myrica to a few species, and treating the others in Morella.

Common names include bayberry, bay-rum tree, candleberry, sweet gale, and wax-myrtle. The generic name was derived from the Greek word μυρικη (myrike), meaning "fragrance."

Characteristics

The species vary from 1 m shrubs up to 20 m trees; some are deciduous, but the majority of species are evergreen. The roots have nitrogen-fixing bacteria which enable the plants to grow on soils that are very poor in nitrogen content. The leaves are spirally arranged, simple, 2–12 cm long, oblanceolate with a tapered base and broader tip, and a crinkled or finely toothed margin. The flowers are catkins, with male and female catkins usually on separate plants (dioecious). The fruit is a small drupe, usually with a wax coating.
