Sorry for not responding sooner - been extremely busy with school lately. One final question, I think I feel better about the rest of this so far. If, in the example gif I posted earlier, the charge is accelerating parallel to the z axis, why isn't there a radiative field in the z-direction? It...

I guess the explanation behind EM radiation is pretty straightforward. I may have overcomplicated it in my head earlier. But I'm still not 100% confident on the directions of the fields/their propagation. For example, how dow we know that in this situation, they propagate in the positive y...

This isn't really a homework question, but I felt it was better suited here than in General Physics. I'm looking for more of a general explanation than anything. I was able to do my homework for this section on my own (mostly), but I feel like I still really have no idea what is actually going...

Ah, okay, that makes sense now. Thanks for your help, and the warm welcome! To start a new thread I just went to the specific forum (Introductory Physics in this case) and clicked "New Topic" at the top right. It's in the same location as "New Reply" on this page.

A satellite of mass 7500 kg orbits the Earth in a circular orbit of radius of 7.3(10^6) m (this is above the Earth's atmosphere). The mass of the Earth is 6.0(10^24) kg. What is the minimum amount of energy required to move the satellite from this orbit to a location very far away from the...
