Question 1

What is a Pendulum Period Calculator?

Accepted Answer

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.

Question 2

How does the Pendulum Period Calculator work?

Accepted Answer

Period T = 2π × √(L / g) Then: L = length of pendulum in metres Then: g = 9.81 m/s² (Earth surface) Then: Frequency f = 1 / T oscillations per second.

Question 3

Can you give an example of how to use the Pendulum Period Calculator?

Accepted Answer

Example: Input Pendulum length 1m on Earth gives a result of T = 2.006 seconds (2π × √(1/9.81) = 2.006s).

Question 4
