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.
Falling may refer to:
"Falling" is vocalist Alison Moyet's only single of 1993 and first single from the album Essex.
The single failed to enter the UK top 40, peaking at #42 for a total of three weeks. Moyet's previous single "Hoodoo" failed to chart in the UK top 100 at all.
A promotional video was created for the single.
Due to the disappointing charting, CBS/Columbia Records insisted that "Whispering Your Name" was re-recorded and re-produced to create a more 'commercial' package for the next single.
The b-side for the single "Ode to Boy" appeared on the same album as well as being released as a single in 1994. The song was written by Moyet and was originally performed by Moyet and Vince Clarke in Yazoo.
The American CD single featured the bonus track "It Won't Be Long (Acoustic)" which is an acoustic version of Moyet's 1991 single.
For the single, the artwork based on a postage stamp is related to the "Essex" album which also carries the same theme.
"Falling" is a song by industrial rock band Gravity Kills from the album Perversion, released by TVT Records in 1998.
"Falling" reached No. 35 on Billboard's Mainstream Rock chart on July 4, 1998. The song was included in both original and instrumental form in the 1998 cross-platform racing video game Test Drive 5.
