A Cause of Inertia

Abstract

Musa D. Abdullahi

A charged particle, moving at a constant velocity, carries along its electrostatic field Eo . But, as a result of finite speed of light, a particle of charge Q and mass m moving at time t with velocity v and acceleration dv/dt, has a resultant of its electrostatic field in the opposite direction of accelerarion. So, a reactive electric field Ea proportional to and in the opposite direction of the acceleration is created. The field Ea acts only on the same charge Q, producing it, to generate an inertial force f= QEa = -m (dv/dt), where m is a constant equal to the rest mass. For a neutral body of mass M, composed of N/2 positive and N/2 negative charges, the inertial forces on the charges add up to Nf =NQEa = -Nm (dv/dt) = -M (dv/dt). This explains the cause of inertia, the tendency of a body to resist acceleration or deceleration, as the result of self-induced reactive forces on the electric charges composing the body, contrary to general relativity. Expressions are deduced for the mass m and energy E of an electric charge Q, in the form of a spherical shell of radius a, in conformity with a mass-energy equivalence law as E = ½ mc2 , where c is the speed of light in a vacuum, in contrast to special relativity giving E = mc2 . The total energy of a particle of mass m moving at speed v, relative to an observer, is Ev = ½ m (c2 + v2 )
