In this lecture we consider one of the oldest and best-studied mechanical systems: the pendulum. We begin with the conservative pendulum model, meaning there is no energy dissipation due to friction or air resistance. We sketch out the phase plane and explain what each of the trajectories means for the physical pendulum. We then conclude with a discussion of what are the effect of damping terms in the model.
