| Abstract: | The autoparametric resonance of a spring pendulum is studied by using the technology of video cameras and computers. By discussing the potential energy of the system, the attributes of the spring pendulum are gotten. The graphs for the displacement, energy and the trajectory of the bob are gotten by recording the position of the bob in real time under different initial conditions. The results demonstrate the agreement between the theory and experiments. |
