ACTIVITY PROPOSAL
CATAPULT
The catapult is an ancient war machine used to launch heavy objects, such as stones or projectiles, towards distant targets. It works by accumulating potential energy in a tensioned structure, releasing it to launch the projectile. It was primarily used in ancient battles, such as sieges of fortresses and naval attacks, allowing armies to attack from a distance, overcoming enemy defenses.
