Most definetly Kinetic energy, maybe Gravitational as well.

The kind of potential energy in a catapult is known as elastic potential energy. The potential energy that is in the catapult is used when you activate the catapult and the rock (or any kind of ammo) fires.
There is no element that is an unlimited energy source. However, hydrogen is the element that powers main sequence stars.
