Acceleration & EM radiation

  1. Jul 2, 2011 #1
    Why does a moving particle particle emit EM-radiation?

    This applies to charged particles that are accelerating or decelerating.

    Whether accelerating charges emit radiation appears to depend on the accelerating force. If the accelerating force is due to a uniform gravitational field, the charge does not appear to emit radiation.

    It seems this question about acceleration of charges and the emission of EM comes up every so often. It is not as straight forward as one may imagine. I suggest the OP read some of the recent threads on this as there is a lot of information in them, too much to repeat here. I do note though that the question was why? I'm not sure that this can be answered in a physics forum.

    Why it depends on the accelerating force? if I "drop electron" from the roof of my house what would happen?
