Catapult Challenge The problem: You need to move some materials from one place to another with the help of a simple machine. Explore vector representations, and add air resistance to investigate the factors that influence drag. Stone-Hurling Catapult, Greece, 400 BCE The Greek Dionysius the Elder of Syracuse, who was looking to develop a new type of weapon, invented the catapult about 400 BCE. Projectile motion. The operators of the ballista have to be concerned about the angle to launch the projectile and the path they had to travel to gauge the landing position of the ballista. Crucial during the Medieval ages and even earlier, these simple machines make use of stored energy to release a projectile, or payload. Add Favorite Remove Favorite More Menu. If the path of the projectile, its launching point, and its target is plotted on a graph, initial velocity can be expressed as x and y components. Create a catapult that will toss a projectile onto a target 3 m away using a minimum of 9 supplies from a given list. It worked by using the energy of a falling counterweight to rotate a beam around a pivot resulting in the release of whatever projectile was loaded into the sling at the other end of the beam. During our physics unit, I have students build craft stick catapults to help demonstrate Newton's Laws of Motion.
