Be careful you don't trip up on the mat.
Be careful you don't trip over the mat.
Be careful you don't stumble over the mat.
Be careful you don't tumble over the mat.
Do all of the above sound copacetic and mean pretty much the same? Thanks.
Nice obscure word you have there!
They are all grammatical, but the last is perhaps something you would only say to a small child.
"Trip up" is different; it's not used literally, but means to make a mistake.
Note that "tumbling" is a synonym of "gymnastics."
These examples imply that the mat is rolled up. If it's lying flat, it seems more natural to say "Be careful you don't trip on the mat."

"Trip" means to stumble because the lower part of your body is obstructed by an object.
You can not use "trip up" in this sense. Trip up has acquired a specific meaning: to make a mistake.
Gymnastics is the well-known Olympic event; tumbling is the same thing, but done without apparatus, and probably implies simpler, less complex activity.
"Don't tumble on the mat" wouldn't mean the same as "Don't trip on the mat."
"Stumble" doesn't have to be literal either. You could say, "I did well on the test but I stumbled on the last question."
Trip is interesting in modern slang. To "lay a guilt trip" on someone means to make them feel guilty about what they've done. To go on an "ego trip" means to have a very high opinion of yourself. A "trip" can also be a hallucination caused by drugs!

Thanks, baqarah, for your elaborate reply.
I would use the second one ("Be careful you don't trip over the mat.")
