Hey guys,
This is my fist post and I am curious enough about this to get a new account. Go on wikipedia for the formula and derivation of the abraham lorentz force: http://en.wikipedia.org/wiki/Abraham–Lorentz_force
Anyway my question is as follows:
Lets consider a charge that I am pulling with a constant force F.
Then obviously by F = ma it has a constant acceleration.
Thus it is radiating some energy.
But according to Abraham-Lorentz force there is no recoil force on the particle, so I spend no energy for radiation.
Because if this was the case I would just take a charge, pull it with a constant acceleration, harvest all the radiating energy, and then absorb the kinetic energy I just applied, and do it again and again. It would be my pretty little infinite energy source. Doesnt that imply any harmonic motion spreads infinite energy?
What is wrong, is it the formula or is it my reasoning?
