Inertial Frames A fundamental postulate of Newtonian mechanics is that  there is a  special class of reference frames, referred to as  inertial,  such that the motion of a particle is completely  determined (for all times), once: The position and velocity of the particle is known at a  given time ( initial conditions ) in one of these frames. The interactions between the particle and the universe  ( forces ) is known; the expression of these interactions  being the  same in all the inertial frames . These postulate are summarized as  = m A  and are referred  to as the  equation of motions  ( EoM Solving these equations consist of solving an i nitial value  problem (IVP):  the integration of a system of 3 second order,  ordinary differential equations with known initial conditions.
