What is Meant by the Physical Pendulum?

In physics, a simple pendulum can be defined as a point mass attached to a light inextensible string and suspended from fixed support. The vertical line passing through the fixed support is the mean position of the simple pendulum. Any swinging rigid body free to rotate about a fixed horizontal axis is called a physical pendulum or compound pendulum. The appropriate equivalent length (L) for calculating the period of any such pendulum is the distance from the pivot to the center of oscillation. This point is located under the center of mass at a distance from the pivot traditionally called the radius of oscillation, which depends on the mass distribution of the pendulum. The time period (T) of a physical pendulum is given by the formula:
T = 2π × √(I/MgD)
I = Center of mass or moment of inertia
M = Mass
g = Acceleration of gravity
D = Distance from the center of mass to pivot.
