What Is A Trebuchet & How Does It Work?

What is it ? a machine used to throw heavy payloads at enemies. It was used in the middle ages.

How does it work ?  It works by using a counterweight, when the weight falls it uses that energy to launch something (ex. A rock or a ball) at high speeds. The counterweight must be heavier than what you are launching to get the maximum speed. 

What was it used for ?  It was used in battle to throw far distances.  It was more accurate than the catapult.
