There is no up or down, as it is no longer relative, therefore the one thing you cannot do in zero gravity is 'fall down.' -Michael Carew
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".
There's most likely no such thing as a "balance force". And if you're thinking of "a set of balanced forces whose vector sum is zero", then gravity is most certainly NOT one of those.
An anti gravity chair, or a zero gravity chair, can be used as an ordinary chair. One can use it in the living room to watch TV, to relax one's body and give one a sense of weightlessness.
The only place where there is no gravity is in space, infinitely far from any mass. To create the conditions that your body interprets as zero gravity, choose one of these: -- Jump from an airplane or balloon. Do whatever skydivers do to minimize your air resistance and fall as fast as possible. That puts you close to zero gravity, but not exactly. -- For brief periods of zero gravity, like 30 seconds at a time, take the training and get a ride on NASA's "Vomit Comet" airplane. -- Get into Earth orbit somehow.
From Newton's Law, the force due to gravity is:F = -mg, (Force = -mass*accgra)-mg is a constant so taking the gradient will give you zero. Therefore, your answer is zero. Now, if you took the gradient of velocity, your answer would be a negative constant.
Walmart, Amazon, and the Oveerstock website all sell zero gravity chairs. There are many different types of "zero gravity chairs" so be careful which one you are ordering.
On the Kelvin scale zero is considered the coldest temperature one can reach: absolute zero. It is the point at which it is impossible to get any colder. 0.00 K is -273.15 oC or -459.67 oF.

the zero gravity pen was originally proposed for a mission. It was the Apollo 5 and up

A probability event that is impossible is one that will not happen, i.e. its probability is zero.
Gravity is affected and effected by mass.
When there's no gravity, light just travels in one direction at the speed of light. Gravity bends the direction at which light travels.
One plus one does not equal zero. One plus one equals two. If you have one thing, then bring another thing in, you get more than what you started with, which would be 2. You cannot have less, like zero.

Velocity is relative to the observer and or objects that are in the area , if your sitting in true zero gravity from your point of view you will be standing still but in-reality your velocity will based on your original thrust. Some one watching you (at a zero velocity) from another location might see you zoom by at the original velocity. So the new question is if that other person has zero velocity and is in zero gravity what time will it be when they look at their watch ? Hmmm
It is an impossible event - which has probability zero.
