Energy Dissipation Through Various Density

[Timothy Jones]

I haven't had the pleasure of being on this site as much as I should be...pardon that. Either way, on with it then:

I would like to begin this article with a question regarding the actual nature of gravity. Relative to massive bodies, it seems that gravity exerts a force that in general, neglecting centripetal effects, causes bodies to fall directly towards the center of the massive object.
However, at present, I'm not looking to determine the rate at which an object would fall. (G) but, but rather the rate at which energy associated with an object is lost in opposition to G, i.e. a vector acting in opposition to G. Would this be Fi+(-G)=Ff at a specific point? (I would imagine that the object would have to increase it speeds to overcome the effect of G. But in doing so would increase its energy, thus increasing its mass, thus increasing the effect of G on it...Not only that, but is G constant in all locations? Or is that constant only relevant on Earth And, if G is not constant, (I.e. in a supermassive object) then would more energy be needed to escape this increased (G)?

I'm asking this because I've devised a form of experiment that has to deal with the dissipation rate of energy as it leaves the surface of a massive body...The ultimate aim is to determine whether or not there is a such thing as "Space Density"...

Any suggestions?

I'm kind of going out on a very long limb to play on: d=rt
If an object is traveling a distance of 5000km from the surface of the earth(neglecting gravitation) at 500km/h, then it follows that it would take 10hrs for the object to reach a height of 5000km.
However, on another planet, with a twice the mass (of similar geometric volume{possibly different composition}) , relative to the surface of that planet, we could construct a coordinate system with the orgin situated at the surface of the massive body. All measurements from the surface of the body would remain the same as those used to measure from the surface of the Earth. (I.e. The coordinate plane would use the same scale to measure km)
Returning to the original: 5000km, which we measured and the object which travels at 500km/h. It is noted then that it took this object 20hrs to travel this distance at 500km per hour...again for simplicity neglecting the effect of G on the object. (for now)
Then, am I wrong to extend the belief that either:
A) The force which acts in opposition to the object direction is a vector whose magnitude and direction causes the energy associated witht the object to decrease? Like attempting to paddle upstream?
or,
B) That the amount of space that is actually present (within the measure of segment 0-5000km) is in actuality 10000?(If we apply d=rt. (in a very general sense)
