Energy

Sound energy:  
           Sound energy travel through media, such as gas liquid or solid, the energy produced by sound vibrations.

Thermal energy:
           In the other word is heat. The sum of potential energy and kinetic energy, in random motion of particles of a material.

Gravitational potential energy is energy an object possesses because of its position in a gravitational field. The most common use of gravitational potential energy is for an object near the surface of the Earth where the gravitational acceleration can be assumed to be constant at about 9.8 m/s²

. Elastic energy is the potential mechanical energy stored in the configuration of a material or physical system as work is performed to distort its volume or shape.

mechanical energy describes the sum of potential energy and kinetic energy present in the components of a mechanical system. Mechanical energy is the energy associated with the motion or position of an object.

Chemical potential energy：

Chemical potential energy is a form of potential energy related to the structural arrangement of atoms or molecules.

cannon

 A cannon works very similar to a gun works. A charge is loaded into the cannon (such as gunpowder) and then the cannonball is loaded in on top of the charge. Wadding is placed into the top of the cannon along with the fuse. The fuse is lit which sets the wadding on fire which in turn ignites the charge. The gases from the charge will rapidly expand causing the cannon ball to fly from the end of the cannon.
