I agree with Demon Goddess insomuch as it is very hard to interpret a card out of context -- both the context of the other cards it was drawn with, and the context of the question asked.
That being said, I think that Judgement in the physical sense is one of the easiest to interpret -- people are judged all day long. Maybe it's legal judgement, or maybe a final decision is being made.
In fact, I'd be willing to say that of all the trumps, Judgement is the one that is most likely to manifest itself in a "tangible" form.
And I say that in quotes because the idea of judgement is just that -- an idea. It's not a Chariot, it's not the Sun, or a Star, or a physical person -- it's an abstract idea, and it "manifest" itself physically, you're going to have to still look at it abstractly.
