Mechanical energy swing because of the work done by the pendulum to oppose these non-conservative forces. That the loss of mechanical energy in a system always resulted in an increase of the system's temperature has been known for a long time, but it was the amateur physicist James Prescott Joule who first experimentally demonstrated how a certain amount of work done against friction resulted in a definite quantity of heat which should be conceived as the random motions of the particles that comprise matter. This equivalence between mechanical energy and heat is especially important when considering colliding objects. In an elastic collision,

Some companies and institutions may be cited are Alcan, Eletrobras, Vale, General Motors, Mercedes-Benz, Brazilian Army, US Air Force and other institutions and industries can be seen on FEM website. FEM also have agreements and sponsorship with other industries and coorporations like Schaeffler Group that also sponsors extracurricular projects. In 1992, inspired by MEJ, was created Motriz - Junior Enterprise of the Faculty of Mechanical Engineering. The Motriz is a nonprofit civil association that aims to optimize productivity and contribute in resolutions to problems in Mechanical Engineering. With the help of teachers of the University, the
