A pendulum's period depends only on its length and gravity — not its mass or swing angle. Solve for period, length, or gravity using T = 2π√(L/g), step by step.
Frequently Asked Questions
What is the formula for pendulum period?
The period of a simple pendulum is T = 2π√(L/g), where L is the length of the pendulum in meters and g is gravitational acceleration (9.81 m/s² on Earth).
Does the mass of the pendulum bob affect its period?
No — for a simple pendulum, the period depends only on the length and gravitational acceleration, not on the mass of the bob, as long as the swing angle is small.
