 * THE STUDY OF HOW A CATAPULT LAUNCHES VARIOUS PROJECTILES**

The purpose of this study was to test the catapult’s accuracy by shooting it at a target. This will explain the catapult’s accuracy when launches at moving objects. The method was to see how many catches a person could get when they stood at different distances. The results were more catches were made at 5 m than any other distance. This is because the farther away a person was the easier it is for a person to aim the projectile at them and for them to catch it because their eyes can track it more easily because it is coming in slower from farther away. Some future experiments that could be done off of this would be a test on a baseball players arm when he launches the ball, and see if that angle is the same as the optimal launching ang le on the catapult because they both use similar physics. This could be tested by having a person throw a baseball or some other object, and have a protractor measure the angle at which the ball is released,and see if that is some where close to the catapult's optimal launching angle. An improvement that could be done on the catapult would be to use different types of leather as a launching string to see if that would increase or decrease the flight time. this would be very useful in determining how far a projectile could go.
