Abstract
A simple construction of a multi-pendulum in the form of a flexible chain of beads is described, together with a straightforward experimental methodology for studying a complex phenomenon—the oscillations of this multi-pendulum initially excited by a bending disturbance. The equipment and experimental procedure are accessible to school students and to educational institutions at the introductory level of physics education. The equipment and experiments are safe and can be rapidly implemented in the educational process. Importantly, the study of oscillations of a multi-pendulum allows for unlimited variability in laboratory results, which is essential for developing students’ independent experimental skills. Any student can construct their own multi-pendulum differing in parameters—such as length, number of elements, method of suspension, etc—from that of a neighbouring student. As a result, it is possible, for example, to measure the damping of oscillations and bending in a suspended multi-pendulum.
