A catapult is a device used to launch objects over a distance without the use of explosives. It operates on the principle of stored energy, which is released to propel a projectile, such as a rock or a small ball. Catapults were commonly used in ancient warfare to attack fortifications or to hurl projectiles at enemies. There are various types of catapults, including the tension catapult, which uses elastic materials, and the torsion catapult, which relies on twisted ropes or sinew. These devices played a significant role in military history and are often associated with medieval siege engines.
