Pendulum Period Calculator
Find the swing period of a simple pendulum.
The period of a simple pendulum depends only on its length and gravity.
The math behind it
T = 2π·√(L ÷ g) for small swings. Mass and amplitude don't affect it.
Worked example
1 m pendulum → about 2.01 s.
FAQ
Does a heavier bob swing slower?
No — mass cancels out of the period.
