Trabalho, energia e potência Mecânica

Synopsis: Professor Galileo Lattes and young Cleber Mariana and Brazil are making a snack at the home of Brazil's family and the matter is energy, its transformations and conservation, with an emphasis on performing mechanical work. The Mechanical Power is also visited, and discuss what they are dissipative forces. A question Mariana produces restlessness: where does the energy for the cyclist can ride your bike? The answer is surprising and culminates with an even more disturbing finding by Cleber, about the nature of matter that forms to your body and is also present in the interior of stars.
