Still shot from the movie Schindler's List The photo above shows Ralph Fiennes as Amon Goeth, shooting prisoners in the Plaszow camp in the movie Schindler's List. In the background is the quarry where Steven Spielberg built a replica of the Plaszow camp.
Thermal energy is the total kinetic and potential energy of the  particles in a substance.    related to the motion of molecules   . Thermal energy. The amount of heat energy in an object depends on three things :  it's temperature, it's mass, and the material it's made from.
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.
