The period of a physical pendulum is measured with its mass in various positions. The period is completely independent of other factors, such as mass. Now, if we can show that the restoring force is directly proportional to the displacement, then we have a simple harmonic oscillator. Introductory Physics Homework Help. To create a pendulum, a weight, called a bob, is hung from a fixed point, called a pivot. As with simple harmonic oscillators, the period T for a pendulum is nearly independent of amplitude, especially if θ θ is less than about 15 °. The pendulum is perhaps the most studied mechanical system in introductory physics laboratories1,2. The time period of a simple pendulum on the surface of a planet does not depend upon.
