0 in science, the force that attracts all objects towards one another: --
Particles are attracted to each other by gravitation.
1 an occasion when someone or something moves or is attracted in the direction of a particular thing or person: --
2 the natural attraction that any two masses have for each other; the force of gravity --
Above all, mainly gravitation and friction influence the form of static nonlinearity.
On the other hand, the force of gravitation and repulsion is already operating between bodies, and precise measuring instruments make it possible to measure heat, cold, and air pressure.
As long as the stellar gravitation sustains the accretion flow, the self-magnetisation of the disk does not saturate until the field strength reaches its local equipartition value.
Since particles in dusty plasmas can interact through both electric and gravitational forces, it is physically relevant to investigate the effect of self-gravitation on nonlinear longitudinal waves.
While the task the model controller has to perform is known, the corrective controller has to cope with model inaccuracies, effects of gravitation, and suppression of system and measurement disturbances.
I myself have tried to approach this by generalising the law of gravitation.
In an appropriate measurement scheme, gravitation should "weaken" over time, proportional to t'1.
The concept of problem gravitation presented above exemplifies this point.
