When I say accelerated, I mean that it's direction is changed, not that it is necessarily slowed down. And my thoughts come from the idea that the work done by an electric field is path independent. As the electron or charged particle comes from infinity, curves, and leaves to infinity, the...

What is it about accelerating charges that releases the x-rays?

But why? Why not just transfer their energy to the things they collide with? And I thought it had something to do with electrons accelerating, not necessarily colliding.

sorry, I made an error. I got that in the frame where 1(4kg) is stationary 2 approaches at .9c, while in the frame where 2(5kg) is stationary 1 approaches at .92c. I did this by writing: m(1) + (gamma2)(m(2)) = 20 and vice versa, solving for the u in the gamma. So plugging in, in the...

Homework Statement Why does it happen? Homework Equations The Attempt at a Solution I read that Bremsstrahlung happens because a charged particle loses kinetic energy as it swings past a nucleus, therefore a photon is released to conserve energy. However, since the electric...

I did that and got reasonable answers (.96 and .95 c, respectively), but I'm not sure where to go from there.

Homework Statement Two particles of mass 4 and 5 kg (respectively) move towards each other. If the mass of the system is 20kg what can you say, qualitatively and quantitatively about the system in the center of mass frame? Homework Equations In the CM frame net momentum is zero...
