Madeline K. The purpose of the study was to find out what makes catapults launch things further and higher. Catapults were invented by King Uzziah the name catapult comes from the Greek word Katapultos they can launch rocks, spears, arrows, and other things catapults are also used on aircraft carriers to launch the plane into the air. Three types of catapults were tested to see which one launched a ball the highest. The Tension catapult launched the ball the highest and the Torsion catapult did not launch the ball far enough for the height to be recorded. The Tension catapult launched the ball the highest because the bottle cap the ball was placed in is slightly angled upward because of the way the instructions say to build it.

 * Abstract**

Instead of keeping one of the catapults wound up it should have been kept unwound and would up only before it was used. Also when the play-doh ball would get launched it would pickup all the things that it rolled over because it was soft and not hardened. One future experiment could be using different shapes of projectiles. Another would be to see if the size of the catapult would affect the distance the projectile launched.
