A catapult is a tool or device that is used to launch or throw objects over a long distance. It is often made up of a long stick or pole that is held down by a tension mechanism, and when released, it flings or throws whatever is attached to it. Historically, catapults were used in warfare to launch large rocks or other objects at fortresses or enemy troops. Today, catapults are often used as toys or educational tools for science experiments.
