That motion transfers into rotational force. The long arm accelerates fast and launches the projectile. No fuel. No engine. Just physics. Potential energy becomes motion in seconds. Ancient engineering understood leverage and timing extremely well. Sometimes the most powerful machines run on gravity alone. Follow f

Physics Made Fun on Instagram: "In 2009, Top Gear built a full-scale counterweight trebuchet to test whether medieval siege engineering could throw a real car. They loaded a small car into the sling, raised a massive counterweight, and released it so gravity could drive the arm through its swing. The launch worked the same way it did in the Middle Ages: stored potential energy in the raised weight converted into rotational motion, then into forward speed as the sling released at the right angle.
