pendulum period

Question

Small angle simple pendulum length L has period:

RankGuru · Accepted Answer

For a simple pendulum (a point mass on a string) making small oscillations ($\sin 	heta \approx 	heta$):
$T = 2\pi \sqrt{\frac{L}{g}}$
- $L$: length of the string from the pivot to the center of mass of the bob.
- $g$: acceleration due to gravity.
Crucially, the period is **independent of the mass** of the bob and the amplitude of oscillation (as long as the angle is small).
