What, exactly, is an average physics student with introductory level programming knowledge going to offer to the video game industry? You know that there are many commercial physics engines that you can just buy, right? (some are even free).
I got into VG industry straight after graduating with MS in Physics (experimental HEP). I wrote the car physics for a racing game series. Specifically, I wrote the whole car dynamics including engine torque, gearbox, suspension, wind resistance, collisions, force feedback and the most important tire model.
These things, I'd say you still need to write in-house even if you can buy commercial engines. Even for those physics implemented in commercial engines, you need someone knowledgeable enough to use.
I was lucky that my excellent domain knowledge (about cars) was a perfect match to the opportunity. My programming knowledge was barely enough for the job, though, with only one course in C and some amateurish programming in HEP. Again, I was lucky, and that is just one data point.
