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.
If you define the "up" direction as "positive", then the acceleration is negative, because it is downward. If you define "down" as positive, then acceleration is negative. You can use any convention; just be sure to be consistent within a particular calculation, to avoid errors.
This appears to be a question about an experiment. We can't tell you what the results of the experiment were because we weren't there.
The only way to produce "artificial gravity" (an imitation of gravity, you might say) is through acceleration. The effects are the same; an experiment won't notice the difference. Acceleration can be provided (a) by going faster and faster, (b) by slowing down, (c) by uniform rotation (an acceleration towards the center).
Acceleration due to gravity is negative when an object is moving up. Accl'n due to gravity is positive when an object is moving down (since gravity acts downwards on an object). ^Acceleration due to gravity is always negative, while the acceleration of the ball upward was positive due to what threw it, not gravity.
If the object is thrown upwards, the vertical acceleration is negative and the horizontal acceleration is zero.

Not at all. However Gravity can impart an acceleration - Gravitational acceleration.
This is a pretty deep question, and it is what prompted Albert Einstein to formulate his theory of general relativity. The basic is the so-called equivalence principle, that acceleration and gravity are the same. Einstein became to understand that there is no local way to distinguish gravity from uniform acceleration. A thought experiment would be you inside a closed up room. Without any way to look or detect anything outside the room you will not be able to distinguish whether the room is inside a gravitational field or uniformly accelerating. No experiment that can be carried out locally can make the distinction either. As such gravity and acceleration has to be the same. In fact acceleration inherits all the hallmarks from gravity, including gravitational time dilatation!
Acceleration does not effect gravity. It is rather the other way round. Gravity can affect the rate of acceleration.
Speed or acceleration have no effect on gravity.
If you mean acceleration due to gravity it is ~9.8m/s2
Gravity acceleration g=GM/r2.
To calculate the acceleration of gravity, time (t) an object falling a certain distance (d) and the acceleration of gravity= d/t
