Period: T2 = 4*PI2*I / MgD
T = Period
I = Moment of Inertia
M = Mass
g = Acceleration of Gravity
D = Length of Central Axis
Simple pendulum, also known as mathematical pendulum, has a mass concentrated on an object (regarded as a mass point) and a constant length.
Compound pendulum, also known as physical pendulum, has an arbitrary size and shape, and the size and shape cannot be ignored.
