Catapult vs. Trebuchet

The exhibit was calling any such catapult a trebuchet.

We had been questioning what the distinction between the 2 weapons had been and after somewhat web search which included Wikipedia, that is what I perceive to be true:

  • Trebuchet:   A trebuchet is a kind of catapult.   The early fashions had been referred to as traction trebuchets and used manpower and ropes to launch a projectile.   Later fashions used pulleys and counterweights and improved the accuracy of intention considerably.

The kind of catapult we simply constructed out of Legos could possibly be described as a traction trebuchet when you imagined the rubber band to be males pulling on ropes.
