Knowlegde in diferential equations and classical laws to dynamicsThis Demonstration shows the motion of a pendulum obeying a classical pendulum differential equation with damping proportional to its angular velocity.The visualization contains an approximate solution to Mathieu's equation , where is the pendulum angle, is time, is a length parameter, and is a damping factor. The diagram on the left is a phase portrait of the system, where the horizontal axis is the angle of the pendulum and the vertical axis is the angular velocityComponente Curricular::Educação Superior::Ciências Exatas e da Terra::Física
