Chemical potential energy：
Chemical potential energy is a form of potential energy related to the structural arrangement of atoms or molecules. Chemical energy stored in the chemical bonds of matter. Chemical reaction is transformed by chemical energy of chemical substance.
Gravitation potential energy:
Elastic potential energy:
Elastic potential energy is the energy stored by the bending, stretching or compressing, stored deformation of an elastic object, such as the stretching of a spring.
Mechanical potential energy:
Mechanical energy is the energy that is an object due to its motion or due to its position. Mechanical energy can be either kinetic energy (energy of motion) or potential energy (stored energy of position). Objects have mechanical energy if they are in motion or if they are at some position relative to a zero potential energy position.
Thermal energy:
Thermal energy is the energy that makes objects hot. It is a form of kinetic energy at the molecular level, the movements of atoms and molecules. For example, Hot water has more kinetic energy then cold water.
Sound energy:
Sound energy travel through a specific medium, the energy produced by sound vibrations. Sound vibrations because waves of pressure which lead to some level of compression. Sound energy is a form of mechanical energy; is not related to any chemical change, but is purely related to the pressure its vibrations cause.
