Abstract This work attempts to understand relativistic gravitation physics in terms of Newtonian ideas and extends some Newtonian results. Chapter 1 reviews the essential structures of the Newtonian and relativistic gravitodynamics. It is demonstrated that a formalism based on a relativistic generalisation of the Newtonian concept of ‘force’ (the N-force) leads to a useful description of gravitational fields. Chapter 2 gives a review of the algorithmic theory available for tidal force computations. It is shown that standard algorithms are unsuitable for developing a physically relevant formulation of N-forces. Chapter-3 develops a convenient operational procedure to analyse that tidal force and define the N-force. Some calculations are given for the charged-kerr geometry and certain special cases of it. Some entirely new features are obtained and their implications discussed. Chapter-4 extends the study to a relativistic analogue of the charged-kerr geometry and the Einstein lagrangian is explicitly displayed in terms of scalar potential. Chapter-5 summarises the results obtained and offers some suggestions for further research.
