Either form is correct, but the shorter form is usually better. Unless you start stringing lots of adjectives together and introduce the possibility of confusion.
But, as I mentioned in a post a few minutes ago, anything is possible in a phrase. That doesn't mean it's right when you put it in a sentence. I agree with Dave that usually the shorter the better, but I could think of contexts where "the velocity of the particle" is superior. Can you?
