Análise newtoniana de um sistema mecânico com uma força dependente da velocidade e a existência de condições para a conservação de energia

Abstract

A mechanical system with a velocity-dependent force is analyzed. It is shown that with very particular choices for the resulting force terms it is possible to obtain the result that the total energy of the system is conserved and that it can be divided into three groups, associated with each direction, that hold as individual conservation laws. © by the Sociedade Brasileira de Física.
