Stroboscopic image of a trebuchet, a type of catapult, launching a ball using the potential energy of a weight falling. A trebuchet is a type of catapult that was used as a siege engine in the Middle Ages. It is sometimes called a counterweight trebuchet or counterpoise trebuchet, to distinguish it from an earlier weapon called the traction trebuchet, which employed pulling men working the mechanism. | |
