A compound pendulum (or physical pendulum) is one where the rod is not massless, and may have extended size; that is, an arbitrarily shaped rigid body swinging by a pivot . In this case the pendulum's period depends on its moment of inertia around the pivot point. The equation of torque gives: where: is the angular acceleration. is the torque The torque is generated by gravity so: where:

Using this equation, we can find the period of a pendulum for amplitudes less than about 15º. For the simple pendulum: T =2π√m k = 2π√ m mg L T = 2 π m k = 2 π m m g L. Thus, T =2π√L g T = 2 π L g for the period of a
For small displacements, a pendulum is a simple harmonic oscillator. A simple pendulum is defined to have an object that has a small mass, also known as the pendulum bob, which is suspended from a light wire or string, such as shown in Figure 16.14. Exploring the simple pendulum a bit further, we can discover the conditions under which it ...

2024/3/28 The pendulum was released from \(90\) and its period was measured by filming the pendulum with a cell-phone camera and using the phone’s built-in time. In order to minimize the uncertainty in the period, we measured the time for the pendulum to make \(20\) oscillations, and divided that time by \(20\). We repeated this measurement five times.
