I'm going crazy, when physicists are studying a gravitational system what they calculate as measures? the total kinetic energy the total potential energy what else? some other examples? i think it is a simple question

i just want some examples of measures that i can use (inspired from the ones that already exist on the gravitational systems)

The similarity measure that i am talking about should be computed on a timescale e.g. T=0, T=100. At the end it would result in 3 histograms(3 systems) that have to be compared.

OK, let me express my self differently, Suppose that you have 3 isolated gravitational systems S1, S2, and S3, is there a means provided by physics, which allows to say something like 'S1 is similar to S2, S2 is not similar to S3 and so on'? (quantify the similarity (comparing two gravitational...

Suppose that you have two isolated systems composed each one of N1 and N2 number of objects (N1 is not necessary equal to N2), respectively. i run the first system from Time T=0 to T=100. i do the same with the second system. My purpose is to compare the evolution of both. If the two systems...

There are some information lost when using a single variable to describe the system, OK. Could you please tell me some measures that i can use (don't care about the loss)

I am repeating myself too, i am looking for a global measure (a scalar would be interesting) that can describe the evolution of the system. i don't want to use the raw position, velocity, acceleration, or something else of each object directly, but something that is computed from all these...

In my formalism, i see the system as a single entity, and i need to compute a measure that describes its state at each instant T. In other words i want to quantify the objects interactions, is there any measure that can do that kind of work or should i create mine?

Hi, I am a computer science engineer and I am trying to simulate the gravity on my computer; several objects with different masses randomly distributed in a Three-dimensional space. I would like to compute a global measure that describes the dynamic of that system at each instant T. My question...
