There are several ways in which a catapult works.
A ocounterweight catapult works by droping a weight strafed to a boom, while the thboom acts like a giant lever. The projectile builds up momentum at the other end (usually in a sling or cup). At the apex of the swing, the projectile is released to travel in a ballistic trajectory.
Tortion machines (onager, balista, scorpion) use a twisted bundle of rope(skein) to push the boom foreward. this method generates surprising amounts of power.

catupults are made by using weights on the bottom than using a long narrow stick to launch
Catapult is a somewhat generic term referring to a number of different machines.
A Trebuchet has a large throwing arm with a pivet near one end mounted up high. On the short end of the throwing arm is a weight, either firmly attached directly to the arm, or in a hanging basket. On the long end of the arm is a sling, which greatly increases range and power.
A Manganol or Onager has a throwing arm often with a sing at one end; the other end is mounted between twisted ropes; the twisted ropes provide the power.
A ballista looks like a giant crossbow mounted sidewise, with a track extending back to hold a massive bolt or rock. It may opperate similar to a bow, in which the arms are bent back; or it may have two arms mounted in twisted rope.

it was built to launch things great distances while the Romans or greek were fighting in war and stuff :D
The catapult was made as a response to large fortifications and castle walls. It allowed very large objects to be fired from great distances in an attempt to bring down defenses.
As far as we know the first catapult was built and invented by the ancient greeks.
Macedonia!!!
The word catapult came from ancient greece. It was also invented there. It means from two seperate words kata pultos
Ziggurats were first built by the Summerians in 5200 BCE.
they were step pyramids built out of stone
Yes, Dionysius invented the "repeating catapult." A device that can hurl heavy objects a far distance with little effort.
