Yes, you can be temporarily detained by police without an immediate, detailed explanation because they only need "reasonable suspicion" (specific, articulable reasons to believe you're involved in a crime) for a brief "Terry Stop," but they must have this legal basis, even if they don't state it, and the detention must be short and investigative, not an arrest. You can ask "Am I free to leave?" to clarify if it's a detention or consensual encounter, but you don't have to provide explanations, and you have the right to remain silent and ask for a lawyer.
