What does the ratio of Force of Gravity to Mass represent and how constant is this value?

That's the acceleration of gravity. It depends on the distance from the
primary object it refers to. It's as constant as that distance is.

What factors does spring constant depend on?
The physical significance of the spring constant is the characteristics of the spring. Hooke's law states that the force needed to compress or extend a spring by a specific distance is proportional to that distance.
What is the difference between specific gravity and gravity?
Specific gravity is the ratio of a substance's density to that of a standard, usually water. Gravity is a force of attraction between two bodies. We usually think of the gravitational force of the earth as the force of attraction for bodies on the surface of the earth, but all objects exert a tiny attraction for each other.
What does it mean to say mass and weight are porportional to each other?
That assumes gravity doesn't change. To say that two quantities, "a" and "b", are proportional means that you can write an equation: b = ka (for some constant "k"). In the case of weight: weight = mass x gravity In this case, "gravity" is the constant. That means that for different objects, the weight / mass ratio is always the same. Close to Earth's surface, this constant of proportionality - the gravity - is approximately 9.8 newton/kilogram. If you go far away from Earth, perhaps onto the surface of other planets, gravity is NOT constant, and the statement that "mass and weight are proportional" is not true.
What is the difference in force of gravity of an object with a mass of 23.5 kg and an object with 14.7 kg?
The ratio of the force of gravity which these objects exert on some other objects are equal to the ratio of the masses. Otherwise, if you want to know the difference in absolute terms (subtracting one force minus the other), you would also have to know the mass of the other object on which they act, as well as the distance. Regarding only the force of gravity ON these two objects . . . -- Assume both objects are in the same place, and that place is on or near the Earth's surface. -- The force of gravity on the more-massive object is (Mbig G) = (23.5)(9.8) -- The force of gravity on the less-massive object is (Mlittle G) = (14.7)(9.8) -- The difference between the two forces is (23.5 - 14.7)(9.8) = 86.3 newtons (about 19.4 pounds).
Would the specific gravity of mercury be the same on the moon where gravity is one sixth of that on the earth?
Specific gravity (Sg) is a value that relates substance x (in this case mercury) to that of water. Notice that Sg is unit-less, thus its a ratio value, and constant. So yes, specific gravity of any substance is the same everywhere, be it earth, the moon, or Pluto. note: Obviously gravity is different on the moon, as you mentioned about 1/6th that of earth. Finding a force of a certain substance on the moon is found by multiplying the density of water by the specific weight of the substance, multiplied by the gravitational pull. Thus, it is not nessicary to change the specific gravity of the substance.
What factors does spring constant depend on?
The physical significance of the spring constant is the characteristics of the spring. Hooke's law states that the force needed to compress or extend a spring by a specific distance is proportional to that distance.
What does constant of proportionality represent?
The constant of proportionality is the ration that relates two given values in what is known as a proportinal relationship. Other names for the constant of proportionality include the constant ratio, constant rate, unit rate, constant variation, or even the rate of change.
What does The ratio between m and v mean?
It is simply a ratio between two variables. There is no information on what measures the letters represent, nor whether the ratio is a constant or variable (eg between Celsius and Fahrenheit).
What does the k represent in the direct variation ykx?
The constant of variation in a direct variation is the constant (unchanged) ratio of two variable quantities. The formula for direct variation is. y=kx (or y=kx ) where k is the constant of variation .

Why do you use a Greek letter to represent pi?
Because the Greeks discovered the fact that the radius and circumference of a circle maintained a constant ratio.
How can you use constant ratios to determine if a relationship is proportional?
set up a proportion and see if both sides simplify to the same answer. If the 2 ratios represent a constant ratio they will simplify into fractions
What is the spring constant of a spring?
The ratio of force applied to how much the spring streches (or compresses). In the SI, the spring constant would be expressed in Newtons/meter. A larger spring constant means the spring is "stiffer" - more force is required to stretch it a certain amount.

What is the constant equal to the ratio of the gas constant to the avogadro constant?
Boltzmanns constant
Is tau a constant?
Yes, τ (tau) is a constant representing the circle constant or the ratio of a circle's circumference to its radius. Its value is approximately 6.283185.
