Simple Pendulum Natural Frequency and Period Equations and Calculator

ωn = [ g / l ] (1/2)

T = 2π ( l / g )(1/2)

Where:

Nodes are indiated in images as a proportion of length l measured from the the left,
g = Acceleration of Gravity, ( 32.2 ft/sec2, 9.81 m/s2 )
l = Length (ft, m)
ωn = Angular Natural Frequency ( rad / sec or Hz)
T = Period (sec)

1 rad/sec = 1/( 2π ) Hz
