Discussione:Levitazione

Alla voce "Levitazione", al secondo capoverso, c'è un errorino da corregere. C'è scritto: ..."i mezzi gassoso"... . Si potrebbe correggere con: "un mezzo gassoso".

Grazie della segnalazione, comunque le voci sono editabili da chiunque cliccando su modifica. Luisa 11:27, 5 set 2006 (CEST)

Una proposta per fare un articolo vero di fenomeno di levitazione, meglio che quello scritto in Wikipedia Inglese:

Levitazione gravifugale fa vedere che tutto universo materiale levita in se stesso.

Gravifugal levitation is the most important kind of levitation. It is a way of existence of whole material universe. I sugest to put it in the article: "Levitation".

Gravifugal levitation

is based in orbiting Earth or some other celestial body at the velocity of satelisation or velocity of levitation. E. g. Astronauts are levitating in their spaceships when they are orbiting Earth at velocity 7,9 km/sec. In such kind of orbiting, gravity functions as centripetal force. Reaction to the centripetal action of gravity is particular centrifugal force. We can call it gravifugal. Earth is levitating in regard to Sun on the base of gravifugal force too, at the orbital velocity of 30 km /sec. Moon is levitating in regard Earth at the orbital velocity 1,002km/sec. Geostationarry satelites, are levitating above certain point at the equator at orbital velocity of 3, 05 km/sec.Its angular velocity equals to that of Earth In opposite to some other kind of levitation (E.g. diamagnetic or electrostatic....), gravifugal levitating bodies are in permanent weightless state. Equation for calculating the value of gravifugal force is F = m v2/ R Where M is mass of body, v is it's velocity and R is distance from Earth's (or some other celestial body) center of gravity. Velocity of levitation is v = root of GM/R. Where G is gravitational constant, M , mas of celestial body, and R is distance from center of celestial body's gravity.--Petarbosnicpetrus (talk) 14:20, 3 June 2014 (UTC)--89.164.210.64 (msg) 22:56, 3 giu 2014 (CEST)--89.164.210.64 (msg) 22:56, 3 giu 2014 (CEST)
