Heat energy
... Evidence of energy is when work is being done. For example: •When a toy car at rest is pushed, work is done on the car if it moves. This work (or movement) is evidence of energy. •When a fan is connected to an electric circuit, it moves, so work was done on the fan. This work (or movement) is evide ...
