KIDS TRIVIA

Detailed explanation-1: -Rockets were first used as actual weapons in the battle of Kai-fung-fu in 1232 A.D. The Chinese attempted to repel Mongol invaders with barrages of fire arrows and, possibly, gunpowder-launched grenades. The fire-arrows were a simple form of a solid-propellant rocket. A tube, capped at one end, contained gunpowder.

Detailed explanation-2: -Rockets have been used as an artillery weapon for centuries, and continue to be used in the modern age after being extensively modernized in World War II. Rockets in the artillery role complement traditional field guns, being superior in some ways and inferior in others.

Detailed explanation-3: -The date reporting the first use of true rockets was in 1232. At this time, the Chinese and the Mongols were at war with each other. During the battle of Kai-Keng, the Chinese repelled the Mongol invaders by a barrage of “arrows of flying fire.” These fire-arrows were a simple form of a solid-propellant rocket.

Detailed explanation-4: -American college professor and scientist Robert Goddard built and flew the world’s first liquid propellant rocket on March 16, 1926. Its flight, though unimpressive (it climbed only 12.5 meters), was the forerunner of the Saturn V Moon rocket 43 years later.
