Zero gravity is not a question of height or altitude, its a question about motion.
You can experience something close to zero G on a roller coaster, air plane, falling elevator and sky diving. All of these involve MOTION. Just as the space station, or space ship is falling around a planet (called orbit) it is the falling, not the distance above the planet that creates zero gravity.

Can vegeta train in 750 times earth gravity?
Vegeta can train in as many times earth gravity as he wants to! Though it may take him a while to work up to some numbers, he'll definitely get there; you can count on it.
Was the zero gravity pen originally proposed for a mission which one?
the zero gravity pen was originally proposed for a mission. It was the Apollo 5 and up
Why are we able to to walk on earth?
The Earth's gravity keeps our feet firmly on the ground.
How does gravity keep the world up?
Gravity is a force of attraction between objects and it keeps objects with mass, like Earth, pulled together. Gravity is what keeps Earth orbiting around the Sun and prevents Earth from flying off into space. It's what keeps us grounded on the surface of the Earth.
How do astronauts do experiments in space with zero-gravity?
Gravity is certainly not necessary in order to do experiments. In fact, there are some experiments that can ONLY be done in zero gravity ... like for example an experiment to determine how seeds decide which way to send roots and where to extend the green shoots when there is no 'up' or 'down', or whether fruit-flies can maintain their sanity in zero gravity and continue their important mating work.

Why is there no such thing as zero gravity?
When you are in orbit you experience a state that is called "zero gravity" or "microgravity" but gravity still affects your motion. An object in orbit is essentially in freefall. A satellite orbiting Earth, for example, is constantly being pulled toward Earth by gravity but it is moving "sideways" so fast that it follows a curved path that misses Earth entirely. The principle applies to any object in orbit.

If a hole is drilled to the center of the earth and a stone whose mass is 1 kilogram at the surface of the earth is dropped into it then what is the weight at the center of the earth?
The weight of an object is its mass times the acceleration of gravity. The acceleration of gravity at the center of the Earth is zero. A 1 kg mass at the center of the Earth still has a mass of 1 kg, but the force of attraction between the 1kg mass and all the other mass around it will add up to zero.
Would you fall off of the earth if there were no gravity?
Gravity is a result from mass (i.e. the greater the mass an object has the more gravity force it will inflict on its surrounding objects). Taking your question literally, if there were no gravity, then there would be no Earth; as to have no gravity the mass of the body must be zero. Therefore you'd be left floating in space. Now if all of a sudden (for some comical and unscientific reason) the Earth's gravitational pull would be switched off, our atmosphere would dissolve, airplanes would continue to fly up into space, and a simple jump would give you enough escape velocity to reach space. So you wouldn't necessarily "fall of the Earth", you'd more or less float away in a Zero-G environment (which happens to mean zero-gravity).
How up is up how down is down how far is far and how near is near?
Up is defined as how far an object rises, and down is defined as objects being attracted by gravity as pertaining to your position on earth. Far is defined as distance away from you and near is defind as how close an object is to you. These latter explainations are interchangable.
Which source of gravity is maintaining all four satellites around the earth?
Satellites of the Earth are held in their orbits by the Earth's gravity. That includes the Moon and all the artificial satellites etc. that are up there.
In the earth where the gravity of the earth becomes zero?
In a perfectly-shaped sphere, with a smooth surface, and composed of exactly the same substance with the same density throughout it, the force of gravity is zero at the exact center of the sphere. That does NOT mean that 'gravity becomes zero' at the center. It means that at the center, for every speck of mass pulling on you in any direction with any force, there's another speck of mass pulling you in exactly the opposite direction with exactly the same amount of force, so the whole thing adds up to zero. In the real Earth, we can't tell exactly where that point is, because the Earth is not a perfect sphere shape, It doesn't have a smooth surface, and we don't know every last little detail about the distribution of mass inside it.
If there is no gravity on the moon why can an astronaut jump up and down as seen in the space shots?
There is gravity on the moon. There is less gravity on the moon than there is on earth, because the moon is smaller than earth. Because the Earth has the mass it has, it has the gravity it has. Because the moon has a lot less mass than the Earth its gravity is about 1/6 the amount of the Earth's gravity.

How is gravity related to distance?
In the middle of the earth there is a core. In the core there is gravity. The farther you go from the core the less gravity you get. That is why in space there is no gravity. comment by rjp the above answer is completely false!i ( neither sound nor valid) Please look up Newton's Law of Universal gravitation the force of gravity exists everywhere in a Newtonian universe . There are rare places where the effects add up to zero
