Energy lost by charge due to acceleration.

SUMMARY

Energy is lost when a charge accelerates, specifically in the form of electromagnetic waves. This energy is derived from the process that accelerates the charge, necessitating additional work to accelerate a charged object compared to an uncharged one. The concept of a "radiation reaction force" is crucial, as it opposes the acceleration of charged particles, indicating that the energy of the radiated electromagnetic waves originates from the work done against this force. This phenomenon is classified as classical rather than quantum mechanical.

We knew energy is lost when a charge accelerates. What is the form of the energy? Which form of energy of theirs are these charges releasing?
 
Physics news on Phys.org
The energy is given off in the form of electromagnetic waves. The energy ultimately comes from whatever process is accelerating the charge. That is, because some of the energy gets radiated away, you need to do more work to accelerate a charged object than an equivalent uncharged object. Thus we speak of a "radiation reaction force" that opposes the acceleration of charged particles. We can say that the energy of the radiated EM waves comes from the work you do against this radiation reaction force.

(Since you posted this in the QM forum, you might note that this is a purely classical phenomenon, not a quantum mechanical one.)
