Thermal Energy
Thermal energy is caused by the increased activity of molecules in any given substance. This process increases the temperature, causing it to rise and be warmer. Subsequently, lower activity or velocity of molecules would make the temperature fall. Thermal energy relies on the laws of thermodynamics, which states that energy in the form of heat can be exchanged from any given object to another object.
Chemical Energy
Chemical energy is also based off of the laws of thermodynamics. With these laws, complicated equations that can be used to figure out chemical energy can be utilized. It is found in food, and energy is stored in the molecular bonds of the food. Thus, it is also a form of potential energy. By the process of respiration, the molecules are broken down and used by various cells of the body.
Electrical Energy
Electrical energy is the flow of electric charge. Examples of electrical energy in action would be energy found in electromagnetic fields and lightning. We have found ways to store this type of energy to further use it for other purposes. Electrical energy can also be generated by burning fossil fuels, which is a popular but non-environmentally friendly way of producing energy.
Sound Energy
Sound energy is probably the most interesting form of energy for me since I'm interested in music. It relies on sound vibrations that travel through a material to produce sound. It depends on the material on what kind of sound it makes. Sound energy is essentially mechanical energy but is not used for energy usages for humans because the amount of energy it produces is rather small.
Other forms of energy include elastic energy, magnetic energy, nuclear energy, and radiant energy.
