Yakk, yes that is so irritating when getting a rotten egg. I haven't for a long time but still I (almost) always brake them in a cup before adding them to what I am cooking.
Yes its a stopped motion, but to be frank this doesn't seem like a very good timing shot. its a normal shot taken with a fast shutter speed and nothing thats timing critical and won't score high because the level of difficult is quiet low
The harsh lighting, combined with egg's appearance of being out of focus detract from this. Also, the only clear "motion" is the small bit of yolk dripping at the top - it doesn't really sell this as a stopped motion shot.
Really hard to tell what is happening with this image. But, I DO have to hold my nose to observe it. :-) Whatever is happening doesn't infer much motion - except one little drip thing on the top of the egg, some ooze that may be coming out of it, and the possibility that gravity is at work. If I were trying to work with a similar subject, I might have tried to drop it on a hard surface and catch the cracking and splattering - maybe some mid-air drops or pieces - something to show that you had really stopped motion. Anyway, that's just my opinion. Good luck with the challenge.
