如何计算Pendulum Period

learn.whatIsHeading

The period of a simple pendulum is the time for one complete oscillation (forward and back). For small angles, T = 2π√(L/g), where L is length and g is gravitational acceleration. Remarkably, period does not depend on the mass of the bob.

2. 2L = length of pendulum in metres
3. 3g = 9.81 m/s² (Earth surface)
4. 4Frequency f = 1 / T oscillations per second
