What is a trebuchet?
A trebuchet is a big siege engine from the Middle Ages that uses a heavy counterweight to fling rocks and other projectiles.
Where did it come from?
The idea of a weight-powered throwing machine existed in ancient times in places like China, and it spread to Europe during the Middle Ages. By the 12th–13th centuries, trebuchets were common on battlefields and in castle sieges.
How does it work?
Think of a long seesaw with a heavy weight on one end. When the weight drops, the other end lifts quickly, pulling a sling that holds a rock. The sling releases the rock, sending it far through the air.
A short timeline
- Ancient catapults and early throwing machines existed before trebuchets.
- Counterweight trebuchets were developed to be stronger and more accurate.
- In the Middle Ages, they were used in sieges to crack walls and launch projectiles.
- Today, scientists and hobbyists build small models to study physics.
Fun facts
- Trebuchets are powered by gravity, not by people turning a wheel.
- They could throw heavy stones farther than many other siege engines.
Safety and learning
Real trebuchets are not used today in warfare; students can build safe, small-models with supervision to learn about levers, gravity, and momentum.
