Pretty much the same way you use pens anywhere else. The "Fisher Space Pen", developed by private industry for NASA, uses a pressurized ink cartridge to push the ink through the barrel to the ball point. This not only enables the user to write in zero-G in space, but also write UPSIDE DOWN here on Earth!

Why is acceleration due to gravity zero at the centre of the Earth?
Acceleration due to the earth's gravity is zero at the center of the Earth because at that point the mass of the earth is equally distributed in all directions, so pulling equally in all directions for a net zero pull. Simplistically, acceleration due to gravity decreases as distance from the center decreases. At the center the distance is zero, hence gravity is zero.
Why their is a zero gravity in moon?
There is not zero gravity on the moon. Any object with mass has gravity (even a cotton ball). However, the more dense and more massive an object, the larger its gravitational pull. This is why, even though a tennis ball does have gravity, it has no effect in relation to the gravity of the Earth. The Moon has something like 1/6th of the Earth's, so if you weighed sixty pounds on Earth (eat something!) you would only weigh 10 on the Moon.
How much zero gravity is there in space?
Zero! that's why it is called zero gravity!
Why isn't an astronaut in our solar system in zero gravity?
An astronaut can never be in zero gravity in our solar system, because there is gravity (usually) from the Earth, and always from the Sun. It is important to distinguish weightlessness from zero gravity. Weightlessness occurs in a gravity environment in which the person is freefalling, hopefully in orbit. In a freefall condition, there is no friction to retard your fall, so you feel nothing pressing against you, and thus you feel weightless..When in orbit around the Earth, an astronaut is in freefall, and is therefore weightless, but there is still gravity. When travelling between the Earth to the Moon, the astronaut is still in orbit around the Sun, and is therefore freefalling weightlessly.
What would happen if the earth did not have the force of gravity?
If the force of gravity of Earth were to drop to zero, to put it in simple terms: Firstly, the whole atmosphere would leave Earth. Meaning all living things would most probably die as many of us can't live without air. Secondly, the moon would most probably float off to space. Without Earth's gravity, it is highly possibly we would never see the moon again. Either that, or the moon's gravity on its own could hold and it would merely be further away from Earth than usual. Thirdly, those not clutching onto something would definitely float off to space as well. People who wants to be lighter would be happier however, as without gravity, everyone's weight is reduced to zero kg, zero grams, zero pounds, etc.
How was space pens used in space?
due to zero gravity of ink
Why fountain pens are not used in space?
Fountain pens depend on gravity to pull the ink down to the nib. In Zero gravity, they don't work.
Does zero gravity possible on earth?
No.
Is it gravity in center of earth ZERO?
Yes. At least, the gravity resulting from planet Earth.
Is there zero gravity at the center of the earth?
Yes; the gravity from different sides should cancel, for a net result of zero gravity.
Is earth's gravity the same on the surface as it is in the center of the earth?
No. At the centre of the earth the acceleration due to gravity is ZERO
Why is acceleration due to gravity zero at the centre of the Earth?
Acceleration due to the earth's gravity is zero at the center of the Earth because at that point the mass of the earth is equally distributed in all directions, so pulling equally in all directions for a net zero pull. Simplistically, acceleration due to gravity decreases as distance from the center decreases. At the center the distance is zero, hence gravity is zero.
Why austraunots create a pen?
the pen which is used on earth is not made considering zero gravity effect if this pen is used in space the ink can flow out easily so astronaut has made a pen considering zero gravity
Did the zero gravity pen change any when it is used on earth?
The zero gravity pen has never been changed or updated because it is almost flawless and nobody has anything to add to it.AnswerThe zero gravity pen relies on the polarity of water in the ink to induce the capillary action to draw ink down to the ball of the pen. Since this doesn't rely on gravity, there is no change when the pen is used on earth.
Where can you exprece zero gravity?
when object fall free like at centre of earth that we call freefall with zero gravity.
Why cant you use pencil in zero gravity?
I think you mean a pen. A pen isn't able to be used in zero gravity because the ink needs to move to the ballpoint where the ink exits. Thus, pens need the ink to flow to the tip of the pen so it comes out the ball roller, which without gravity won't work as well.
Does the earth atmosphere protect us from zero gravity?
No
