Bomb

A bomb is an explosive weapon that uses the exothermic reaction of an explosive material to release energy suddenly and violently, causing damage through pressure waves, flying fragments, and heat. Bombs using gunpowder first appeared in East Asia, with early exploding devices recorded in China around 1000 AD and iron cased explosive bombs documented by the thirteenth century. The English word bomb comes from the Latin bombus, itself from a Greek word meaning a booming or buzzing sound, a description of the noise of detonation. Modern usage separates military bombs, typically dropped from aircraft, from civilian explosive devices used in construction or mining, and from improvised explosive devices built by irregular forces outside any military supply chain.
