What is the deference between black powder and flash powder regarding the power, detonation velocity and stabi?

Can anyone tell me that what is the deference between black powder and flash powder regarding the power, detonation velocity and stability? If a packet containing black powder fall from 10 feet distance to surface then can it blast?What is the deference between black powder and flash powder regarding the power, detonation velocity and stabi?
Black powder is carbon, sulfur, and potassium nitrate. When is combusts it produces mostly soot and little gas. Very shock stable





Flash powder is and oxidizer and a metal like potassium perchlorate and aluminum, same as a solid rocket booster. More flash and no soot. Shock sensitive, usually the two components are mixed just before use.





Bother are Deflagrates, they burn, not explode, sotheirr combustion rate is sub sonic. Dropping a bag of black power,althought not a good idea, most likely wont go off. Mixed flashpowder will ignite.





If contained and ignited both will explode, this is how fireworks work. But the explosive powder is lower than conventional explosives which is why they are used in fireworks.What is the deference between black powder and flash powder regarding the power, detonation velocity and stabi?
I'd like to add that flash powder, while NOT a high explosive, has been categorized as such by the ATF. Which mean it's not legal to make flash powder without a Type 20 High Explosives Manufacturing License from the ATF.
