â¢ Mechanical energy is the ordered movement of the molecules as a single unit. Thermal energy is the random movement of the molecules. â¢ Mechanical energy can be 100% converted to thermal energy, but thermal energy cannot be fully converted to mechanical energy. â¢ Thermal energy cannot do work, but mechanical energy can do work. â¢ Mechanical energy has two main forms, namely kinetic energy and potential energy.
Thermal energy is the energy that comes from heat. When thermal energy is transferred, it is called heat. Heat is a temperature and is measured in degrees of Fahrenheit or Celsius. An object can contain thermal energy, but it cannot contain heat. Thermal energy most commonly comes from fossil fuels such as coal or gas. In addition, thermal energy can be generated by resources such as biomass, solar and geothermal. Biomass - this is a fuel generated from organic materials.
