Gravity is constant in that the rate of change of the force due to gravity is constant.

I think you need to study anti-logic to quantify Fryon.

That only works in specialized circumstances; perhaps gravity is constant in that that G, the gravitational constant, is constant.

Well, I'm definately a 'Constant', and that's alot better than being a 'Variable' IHMO.

hmmm,.. but then again my post count is always changing, so I might be a 'variable' disguised as a 'constant'.

Come to think of it, many of the people here would best be described as 'Regulars',..

So I'm happy to announce I'm a regular guy.

Cheers!

P.S. I thought Gravity was 'relitive' not 'constant'. And if I'm not wrong it's relitive to mass, right?

Force from gravity is relative, sure:

F = G((M * m)/(d^2))

Where F is the magnitude of the force due to gravity, G is the gravitational constant (it is only sort of constant, as it depends on the units used), M and m are the two masses involved and d is the distance between the two masses. The direction is towards the other object.

Also, as Acceleration = Force/Mass, the acceleration is also relative.

Yeah, a variable can be static, or it can be const, and also a variable can be a member.

In this forum, you can be bailed out at any given time when you stumble into a scientific discussion. Gotta love it!

Not sure who this Fryon is... but it is quite impossible to quantify a person.

Is the gravitational constant really constant?

To the best of my knoweledge, within a given system of units (e.g. metric: meters, seconds, kilograms; "English": feet, seconds, slugs) the gravitational constant is constant. However, we have only had the tools to measure it for a fairly short period of time, and only on Earth.
