Is black powder the same as gunpowder?

Yes, black powder and gunpowder refer to the same substance, which is a mixture of saltpeter (potassium nitrate), charcoal, and sulfur. It is one of the earliest known chemical explosives and was historically used in firearms, cannons, and fireworks. While the term "gunpowder" is often used more broadly to refer to various types of propellants, black powder specifically denotes the traditional formulation of this explosive.
