    It is called thermal energy that type of energy that anybody has at a temperature above zero. This condition represents an extensive quantity and is directly proportional to the temperature that the body generates. Thermal energy is the kinetic energy of the microscopic motion of particles, a form of a disordered equivalent of mechanical energy; refers to the energy contained within a system that is responsible for its temperature. The faster the particles move within an object or system, the higher the temperature that is recorded. Thermal energy is a term used loosely as a synonym for more rigorously-defined thermodynamic quantities such as the internal energy of a system. Heat is the flow of thermal energy.

    The sum of the kinetic energy of all the particles of a system constitutes an energy form of matter called thermal energy.

    In the context of mechanics problems, thermal energy play a role in ensuring the conservation of energy. Almost every transfer of energy that takes place in real-world physical systems does so with efficiency less than 100% and results in some thermal energy. This energy is usually in the form of low-level thermal energy. Here, low-level means that the temperature associated with the thermal energy is close to that of the environment. It is only possible to extract work when there is a temperature difference, so low-level thermal energy represents ‘the end of the road’ of energy transfer. No further useful work is possible; the energy is now “lost to the environment.”

    Thermal energy can be produced from friction, drag, combustion, and chemical reactions. Thermal energy can be effectively stored and retrieved by means of sensible heat and latent heat principles. The other way of storing and releasing thermal energy can be performed through chemical reaction principles.
