A trebuchet is a catapult that uses a counterweight to supply the energy for throwing. They were used in the Middle Ages for attacking castle walls. In this project St. Gregory students build their own trebuchet and investigate how design changes like changing the length or the mass of the counterweight will affect the distance that a projectile can be thrown by a trebuchet.
