A catapult is a device used to launch a projectile to a great distance without using explosive devices. Catapult has been used since ancient times and has been proven the most effective mechanism during warfare. This weapon is used to hurl projectiles to a distance. This is a simple device that can store energy to release a projectile when required. Catapult can be classified as tension catapult, torsion catapult or gravity type catapult. Through the process of sketching, constructing and testing, a simple catapult was constructed. The catapult was modeled on design software and proper testing for distance and average velocity was done.

Keywords: Catapult, tension type catapult, torsion type catapult & gravity type catapult.
