By analogy, it hasother uses not directly related to gravity. Contents 1 Sensation 2 Accidents 3 Classical physics 4 Mathematics Sensation A sensation of falling occurs when the labyrinth or vestibular apparatus, a system offluid-filled passages in the inner ear, detects motion. The same system also detects rotarymotion. 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 bones have grown brittle. The UK government estimates that about3,000 British people over 65 die as as of a fall each year, and are the fourthmost significant cause of serious injury or death in the home. Classical physics 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 attractiondue to gravity. This is known as weight. If the force of gravity is not equalized by anopposite 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 isdirectly proportional to the mass ofthe planet. The planet will also fall towards the center of the syste... 3) " Va" -- As it applies to Potomac Falls Va VA may mean: the SI volt-amp unit of apparent power the USPS postal state code for Virginia (formerly Va.) .va , the ISO country code and ccTLD for the Vs tican City Va is another name for the Wa people of China the U.S. Department of Veterans Affairs, formerly the Veterans Administration ...
