The trebuchet, a subset of the catapult,
differs primarily in its motive force.
Trebuchet vs Catapult
The stone throwing catapult (Figure 1) was an ancient
invention powered by the torsion of a bundle of twisted cord or horsehair
known as skein, as shown in Figure 2.
The hinged counterweight trebuchet (Figure 3) was a more
recent medieval development powered by gravity or, more specifically, a
stone or earth filled cabinet known as a counterweight, as shown in Figure
4.
