Objective: Description of elliptical oscillations of a string pendulum as the superimposition of two components perpendicular to one another
Depending on the initial conditions, a suitable suspended string pendulum will oscillate in such a way that the bob’s motion describes an ellipse for small pendulum deflections. If the motion is resolved into two perpendicular components, there will be a phase difference between those components. This experiment will investigate the relationship by measuring the oscillations with the help of two perpendicularly mounted dynamic force sensors. The amplitude of the components and their phase difference will then be evaluated.
