Classification: 16.9.

Nature of problem:
Flexible representation of the classical relative motion of two particles interacting through a general central force.

Solution method:
A general terminology of states and frames is introduced which allows changes from one state or frame to another to be defined. The frame changes are analytic. The state changes are made by solution of Nweton's equations of motion using a fourth-order Runge-Kutta formula.

Restrictions:
Limited to central forces.

Running time:
This depends on the form of the potential, the boundary conditions and the integration time specified.
