It's a place where gravitational force has been accurately measured, usually marked with a bronze plate with the results. Here's a link: http://www.holoscenes.com/cgi-bin/moin.cgi/gravity_station
The International space station is constantly falling towards Earth under the pull of Earth's gravity (Just like any other object - gravity does not stop when you reach space!). However the Station is moving very fast horizontally and, as the Earth is a sphere, this means that as it falls its path takes it round the Earth in a circle - it is in "orbit". This means that if you are in the space station you are falling as fast as gravity can pull you and therefore you do not feel the pull of gravity, making you weightless.
There is no real such thing as a room without gravity, but you can create the illusion of zero gravity by accelerating downwards very quickly (i.e. in an aeroplane). This is one of the tests that they use for training astronauts! In addition: there is now a gravity-free plane! It's the "Zero G" plane and simulates no gravity as it dives. It is still extremely expensive, but provides a "once-in-a-lifetime experience".
The centripetal force that keeps the International Space Station in orbit around the Earth is due to the gravitational pull between the Earth and the space station. This gravitational force causes the space station to constantly fall towards Earth, but its tangential velocity keeps it moving sideways, resulting in a stable orbit.
In the unlikely event you find yourself in a freely-falling elevator, then the relative motion of the pencil is among the least of your concerns.If the pencil were hovering, then both you and the pencil are in free-fall.A condition that is not permanent for you and me, and it will eventually stop.This is commonly referred to as zero gravity, but should be called zero net gravity, for in your space station, gravity still acts - but it is exactly balanced out by centrifugal force. If gravity actually became zero, then your space station would speed off into space.
To simulate Earth's gravity on the space station, the centripetal acceleration created by rotation must equal the acceleration due to gravity on Earth (9.81 m/s^2). Centripetal acceleration is given by a = omega^2 * r, where omega is the angular velocity in radians per second. So, omega = sqrt(g/r) = sqrt(9.81/110) = 0.31 rad/s. The frequency of rotation can be calculated as f = omega / (2 * pi) = 0.31 / (2 * 3.14) = 0.049 Hz.
By spinning, the centripetal force creates artificial gravity on the space station.
because, gravity pulls ISS(Inter national Space Station)
no.
I'm not sure if it's ever measured, but it could be approximated by calculating the surface gravity of a spherical asteroid of equal mass and dimensions.Assuming the mass of the International Space Station is 450 000 kg (M) and its mean radius is about 30 meters (r) , the surface gravity would be g = MG/r2 = about 0,00000003337 m/s2 (about 30 nanometers/square second).For comparison, Earth's surface gravity is about 9.81 m/s2, so the gravity you would experience standing on the surface of the International Space Station is about 0.3 millionth of a percent compared to earth. It's certainly too small a gravity to hold you attached to the station if you were standing on it.If you're inside the space station, in the center of the station, there is zero gravity because you are in the center of gravity because the mass of the station is situated around you.Panu, M.Sc.
As of 2010, artificial gravity technology has not been invented.

Yes, there is gravity on the International Space Station (ISS), but it is not due to the station being in Earth's orbit. The sensation of weightlessness experienced by astronauts aboard the ISS is because they are in a state of constant free fall towards Earth, creating the effect of microgravity.
Gravity on the International Space Station is created by its continuous free fall towards Earth, which gives the sensation of weightlessness to the astronauts onboard. As the station orbits around the Earth, it falls towards the planet due to gravity but moves forward fast enough to miss it, essentially making it in a state of perpetual free fall.
The force of gravity keeps the space station in orbit as well as inertia that keeps the space station moving in a straight line.
Temperature and gravity.
Yes, it's held in orbit by gravity.
