catapult
A catapult is a device used to launch objects over a distance without the use of explosives. It works by storing potential energy—often through a twisted or stretched material—and then releasing it rapidly. Traditionally used in warfare, catapults could hurl stones or projectiles at enemy fortifications. They come in various designs, such as the trebuchet and the mangonel, each utilizing different principles of mechanics. Today, catapults also serve educational purposes in physics demonstrations and can be found in competitive settings, like building models for contests.

A catapult is a device used to launch objects into the air, relying on stored energy to propel them. It typically consists of a lever and a frame, where potential energy—often from tension or gravity—is converted into kinetic energy when the lever is released. Catapults were widely used in ancient warfare to hurl stones or projectiles over walls during sieges. Today, they serve educational purposes in physics demonstrations and model construction, illustrating principles of motion, force, and energy transfer.
