Guys check this, its really interesting. Let's imaging a charge attached to a spring of charge q and mass m, and imagine strecht the spring a distance a, from its equilibrium position. Now the charge its being accelerating by the spring and therefore by maxwell electromagnetic theory it will radiate, the energy that the charge will radiate , will come out of its mechanical energy, and because of this the charge should stop, after radiated all the initial mechanical energy. But if i write the equation of motion, i only have the force of the spring accting on the charge, so if i solve the equation of motion, this equation will predditc that charge will oscillate for ever. So from the fact that the charge is radiating, i should consider some dissipated force, in order to reproduce in the equation of motion, what energy conservation says. But if the charge its alone in the universe, its just being influence by the spring, and nothing else, so perhpas its an auto force? can anyone tell me, How should i write my equation of motion, and what its this dissipative force I am not considering?
