Resumo
The dynamics of a spring pendulum varies according to its total energy and a parameter, called $f$, that accounts for its physical characteristics: pendulum mass, spring stiffness constant and spring unstretched length. We build the Poincaré sections of the system and analyze the order-chaos-order transition that it undergoes as we change the control parameter f.
