I just realized that electromagnetic radiation contradicts my statement. As soon as the charges get accelerated, then the sum of linear momentum plus electromagnetic momentum is not conserved anymore because the momentum flux is non-zero at infinity. My initial approach doesn't make sense due to...

I don't know why it doesn't seem to be working EDIT: I needed to refresh my browser

When you write out the equations of motion for a system of two isolated charges, you can add both of the equations and get the increase in the particles linear momentum on one side. On the other side, you get the sum of all the forces between the particles. I understand that this sum of forces...

That doesn't necessarily mean that interactions propagate at a finite velocity. For now you could interpret such dependence as the presence of a force which is stronger or weaker depending of the particles' velocity. When you get to non-inertial frames of reference, you will learn about Coriolis...

Both of those cases sound interesting to me, I didn't even realize that such a distinction could be relevant here.

Hello. Let's suppose that we have a Michelson interferometer to study interference patterns of light. This time we use plane waves. If we set the whole thing up so that the two separated beams have a phase difference of π when they superpose, destructive interference ensues. Since we're...
