In the elasticity of it being held down. It depends on which catapult mechanism, all catapults are powered by potential energy; for example the simple catapult is an elasctic band that is pulled back converting the energy used to pull it back (usually muscle power) into the potential energy in the stretched elastic band.
It depends on the type of catapult but in broad terms:
During loading some physical effort is put in to pull the catapult into its firing position. Traditionally human energy but it could be an electric motor or some other form of energy. The energy is stored, typically in the form of spring compression. Some energy is lost as heat and sound.
When the catapult is fired the spring energy is converted into movement (kinetic) energy of the fired item. Some energy is lost as heat and sound.
From what I read about catapults, it seems that they store energy in torsion springs. The springs, of course, must be wound up - for example, with muscle power.

It uses elastic energy.
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.

kenetic energy
kinetic energy to gravitational potential energy
I think the kind of energy you are looking for is mechanical energy.

A mangonel is a kind of catapult.

A catapult is actually a compound machine.
They used the catapult for war.
It relied on a torsion (twisting) to provide the energy for the throw, as opposed to a counterweight.
To achieve the most distance, you should set your catapult to release a projectile at 45 degrees angle relative to horizontal plane.Higher stored potential energy doesn't neccesarily mean more distance. Distance of the shot depends mainly on starting velocity, which in turn depends on rate at which catapult transfers the energy to the projectile. A limit for that depends on construction of the catapult.
You use a catapult to launch things into the air.
