N-body problem
N-body problem is a draft programming task. It is not yet considered ready to be promoted as a complete task, for reasons that should be found in its talk page.
wp:N-body problem is a problem of physical description of mechanical system of N interacting objects. System is described by newton's law with continious combined force from other bodies.
Exact formulation of first mechanical problem is, given initial coordinates and velocities , to find coordinates and velocities at with accuracy more then given relative value
As well known from physical background, only the choice of N=2 can be analythically solved.
