Derived terms

The article is about the act of falling, for the novel by Anne Provoost, see Falling (Provoost novel)

Falling is movement due to gravity, but also has other uses not directly related to gravity.

Sensation

further Sense of balance A sensation of falling occurs when the labyrinth or vestibular apparatus, a system of fluid-filled passages in the inner ear, detects motion. The same system also detects rotary motion. A similar sensation of falling can be induced when the eyes detect rapid apparent motion with respect to the environment. This system enables us to keep our balance by signalling when a physical correction is necessary.

When a human is in free fall in an orbiting spacecraft, or in an aircraft in a steep dive, the sensation of falling is constant, and the sensation of there being an "up" and a "down" is missing or much attenuated. Some medical conditions, known as balance disorders, also induce the sensation of falling.

Accidents

Falling is a major cause of personal injury, especially for the elderly whose vision, nerve conduction and muscles are weaker, whose vestibular sense is diminished, whose neurological responses are extended, and whose bones have grown brittle. Builders and miners represent worker categories representing high rates of fall injuries. The WHO estimate (2002) that 392,000 people die in falls every year. In 1972, Vesna Vulović survived a fall from 33,000ft without a parachute.

Falls in the workplace

Falls from elevation hazards are present at most every jobsite, and many workers are exposed to these hazards daily. As such, falls are an important topic for occupational safety and health services. Any walking/working surface could be a potential fall hazard. An unprotected side or edge which is 6 feet or more above a lower level should be protected from falling by the use of a guardrail system, safety net system, or personal fall arrest system. These hazardous exposures exist in many forms, and can be as seemingly innocuous as changing a light bulb from a step ladder to something as high-risk as connecting bolts on high steel at 200 feet in the air. Falls are the second leading cause of work-related death in the U.S. In 2000, 717 workers died of injuries caused by falls from ladders, scaffolds, buildings, or other elevations.

Elderly

Stephen Lord at the University of New South Wales studied 80,000 elderly persons in Australia and found that the risk of falling increases for any who are taking multiple prescription medications and for all who are taking psychoactive drugs. This increased risk was demonstrated through the use of a variety of balance and reaction time tests. Inexplicably, the older men when matched with women of identical height, weight, and age, on average, performed measurably better in all of the balance and reaction time tests.

Classical physics

further Gravity Falling is descent under gravity. All objects have mass and in the presence of sufficiently massive objects such as planets or moons they experience a strong attraction due to gravity. This is known as weight. If the force of gravity is not equalized by an opposite force directed away from the planet, the object will start to fall towards the center of mass of the system--in effect, towards the center of the planet. The acceleration of gravity is directly proportional to the mass of the planet. The planet will also fall towards the center of the system but, if the object is much less massive than the planet, this motion is imperceptible.

The way in which an object moves under gravity (not necessarily a descent), in the absence of other forces, is known as free fall, and is described by a conic section whose parameters are dependent on the object's initial velocity. If the speed is above the escape velocity, and the object has no downward vertical component, the force of gravity is not enough to reverse the motion away from the planet and it will continue indefinitely on its path away from the planet. Otherwise it will fall back towards the planet and may go into orbit around it or collide with it.

In the presence of an atmosphere, the conditions for free fall are broken and the object will experience atmospheric drag, and the speed at which it falls towards the planet is subject to a terminal velocity when the force due to drag equalizes the force of gravity. Note that in common usage the term free fall does not take account of atmospheric drag. Claire and Adrienne the act of being amazing

Mathematics

In mathematics, the word falling describes a scalar value that decreases with respect to time or another variable.
