Abstract
An inexpensive driven physical pendulum is described for classroom demonstrations, which clearly shows free and forced oscillations, as well as the transient process leading to the steady-state regime of forced oscillations. An advantage of this pendulum is that it is possible to control the decay constant by the use of magnetic braking. A data-acquisition system1 collects the data and displays the oscillations on a computer screen.
