This paper studies, for a specific oscillatory system composed by a pendulum\nconnected to a seesaw, how the geometry of the different mechanisms of energy\nintroduction conditions the resulting movement, to achieve both a greater\namplitude of oscillation due to a change of velocity and an acceleration in its\nmovement. The different configurations that give rise to the acceleration of\nmotion are therefore analyzed. The study is carried out from a kinematic point\nof view, theoretically simulating an energy increase in the system and\nanalyzing its response in terms of angular velocity and of modification of\napparent weight. Subsequently, the force diagram necessary to generate the\naccelerated motion is analyzed. The magnitude of the external force to be\napplied and its dependence on the direction and angular instant in which it are\nexerted is evaluated. It is observed how for some specific configurations this\nmagnitude is negative, implying that the system is capable of accelerating when\nsubjected to a brake or load on it.\n
