The paper is an attempt to give physical explanations for the causes of electrostatic, gravitational and inertial forces. This is done by considering an electric charge, of magnitude Q, as an impregnable spherical shell, with its radial field pulling the surface, equally outwards. A stable structure, such as an electron, is maintained with constant radius a, energy E and mass m. It is proposed that the electrostatic field lines of force from adjacent charges, Q and K, are curved to give a resultant pulling force of repulsion or attraction. The electric field due to charge Q, at the location of another charge K, and the field due to K at Q, are curved, becoming slightly reduced for force of repulsion and similarly increased for force of attraction, to make for a net gravitational force of attraction. A charge Q moving at a constant velocity v bears its radial electrostatic field E, without distortion. But, due to the finite speed of light c, change in velocity of Q is not instantaneously communicated to all the fields. Consequently, the lateral field lines become curved, to create a reactive electric field E opposed to acceleration. The field E is supposed to act at time t, on the charge Q, to create the inertial force QEa = -m(dv/dt).
