If it is a cannon BALL (without any explosives in it) is would store no energy. (with explosives= chemical).
Firing the cannon. Fuse ignite the propellant (火藥) --CHEMICAL ENERGY
This produce HEAT ENERGY
Heat causes air to expend in the chamber (炮膛) to propel the cannon ball--KINETIC ENERGY
The cannon ball goes forward. But it may also go upwards--POTENTIAL ENERGY
You can hear the shot and see the muzzle flash (炮口火光) so that's SOUND and LIGHT energy.
Overall, CHEMICAL (propellant) > HEAT(chamber) > KINETIC (cannon ball) +POTENTIAL (cannon ball)+SOUND (cannon)+ LIGHT (cannon)
