Ballistas
Gravity and air resistance are key forces acting on most catapults. Depending on the type of catapult, there will also be either tension or torsion. Both are forms of elasticity. Catapults with torsion acting on them are usually ballistas while catapults with tension acting on them are simply called catapults.
