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.
Heat or Thermal energy: The energy radiated to Earth from the sun is called thermal or heat energy and is the same energy form as boiling water. For example, boiling water possesses thermal energy, which is the collective, kinetic and potential energy of the vibrating molecules in the water.eat or Thermal energy: The energy radiated to Earth from the sun is called thermal or heat energy and is the same energy form as boiling water.
