Main Question or Discussion Point
I am abilogist who recently have to describe medical imaging....In this while explaining Bremsstahlung radiation, I am faced with a question. When a charged partcile like electron approaches another charged particle like nuclues in this case, does it undergo acceleartion or deceleration? since it experiences an attraction from nucleus, why does it slows down and not gains velocity? and what is the reason behind this phenomenon?
