__On the Interactions of Point Masses
__

The formula for the
gravitational field (** g**) of a
point mass (m

** g**(

In this equation

__v___{ret}
and __a___{ret} are m_{1}’s
*retarded* velocity and acceleration
respectively;

The formula for m_{1}’s
gravitomagnetic field is

In order to calculate the
motion of m_{2}, Newton’s relativistically correct 2^{nd} law
must be applied.

** F**
= d(m
