The specific gravity is the ratio between the density of a material and the density of water, at a given temperature and pressure.
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.
Acceleration due to gravity is the rate at which an object accelerates towards the Earth when falling freely under gravity. It has a constant value of approximately 9.81 m/s^2 near the surface of the Earth.
The center of gravity of a body is the point at which the entire weight of the body can be considered to act. It is the average location of the weight distribution in a body, where the force of gravity can be assumed to act when analyzing the body's motion or stability.

Weight is a measure of the force of gravity acting on an object. It is commonly measured in units such as pounds or kilograms. Weight is different from mass, which is a measure of the amount of matter in an object.
Define
If you were going to treat all of the forces acting on a plane at a specific point that point would be the CG (Center of Gravity), which is usually measured in inches aft of the datum (a non-physical point used by engineers to define the center of gravity).

Isaac Newton is credited with defining gravity in his work "Philosophiæ Naturalis Principia Mathematica" published in 1687. Newton's law of universal gravitation states that every mass attracts every other mass in the universe with a force proportional to the product of their masses and inversely proportional to the square of the distance between them.

There is no specific interval, especially if you define a decrease as a negative increase.
