Hmmm.... If U &prop; E2, E &prop; a and a &prop; &omega;, how can Uavg not be dependent on &omega; ?

I believe that the key word here is AVERAGE.

Why ? If Emax depends on &omega;, then so should Uavg.

Have I missunderstood something ? Will the amplitude of E increase when the oscillating charge accelerates faster ?
