25 seconds I thought it would be longer. The free-fall speed of the human body is 120mph. So, the aircraft has to dive and reach a vertical speed of 120mph. If you run the calculations with the a/c starting at 45,000 feet altitude, you would expect the aircraft could "fall" for 4 minutes. But, of course, you have to allow time for the aircraft to pull out of the dive and a little margin for safety. Then there are structural limitations on the aircraft. What is amazing is that the weight-less scenes in the movie "Apollo 13" were filmed using a "vomit comet". This required them to fly over 58,000 dives. The weightlessness is not caused by diving, but by flying upward into a curve (I believe it is called a hyperbolic curve). This curve essentially imitates what a body would do projected upward into a similar curve. I'm sure it's a great deal safer and less stressful (on body and plane) than any "dive" method.
Zero G conditions are achieved just before, during, and after the top of the above mentioned curve. For a informative diagram of this phenomena see the Web Link to the left.
The word "vomit" is in the King James Version of the Bible 8 times. It is in 8 verses. Please see the related link below.
Being sick (vomiting or trying to vomit).
You will most likely vomit, or have a very sore throat.
Bulimia is a psychological disorder that compels individuals to forcibly vomit their meals, in order to prevent gaining weight. Some physical diseases can also cause nausea and vomiting.
It's akin to vomit i.e. to bring up food in the stomach back to the mouth cavity or out of the body entirely. Whereas humans vomit to get rid of bad food, other animals regurgitate as part of normal digestion. For example, cows 'chew the cud'.
It is important cause they will vomit
Through intensive training. In fact, there is an old aircraft, a Comet, whose interior is cleared of seating and other stuff and its walls are cushioned. The aircraft climbs to a great height and then drops so that scientists inside are given a brief experience of weightlessness. You may be interested to know that this aircraft is known as the "vomit comet".
Some words that rhyme with "grommet" include "comet," "vomit," and "bonnet."
it is called vomit comet.

No; creating zero gravity on Earth is not possible, unless the lab is at the center of the Planet or is free falling; like an aircraft accelerating towards the ground, namely the Vomit Comet. Stephen Hawking took that ride!
Training in the vomit comet, or reduced gravity aircraft, allows astronauts to experience microgravity conditions similar to space flight. This helps them prepare for the feeling of weightlessness and adapt to the challenges it presents, such as disorientation and motion sickness. By practicing in this environment, astronauts can improve their ability to work effectively in space and minimize the risk of nausea during the mission.
Fish vomit from changing water conditions or from eating something bad.
A "vomit comet" is an aeroplane that briefly achieves zero G, allowing people and prospective astronauts to experience weightlessness.In general, 65 seconds of flight will achieve 25 seconds of weightlessness.Weightlessness produces nausea and sickness (vomit) in two out of three people and thus the aeroplane earns it's nickname.Zero Gravity Corporation in the US, will allow you - for a fee (Probably including a cleaning change) - to experience this.See related link for more information
The "vomit comet" got its name due to the weightless or microgravity environment it creates during parabolic flight maneuvers. The experience can induce motion sickness in passengers, leading to the term "vomit comet."
Flying in a parabolic arc is the best we can do presently. Astronauts have to take such training aboard the "Vomit Comet"
Technically not real free-fall, but close enough to put the point across: -- jumping or diving from the high board at the pool -- the first several seconds of sky-diving -- the 'vomit comet' aircraft that flies parabolic arcs and gives its passengers, such as astronauts in training, several seconds of weightlessness.
