Simple Pendulum Calculator

Find a pendulum's period and frequency from its length.

Calculated Output

Period 2.006

Frequency (Hz) 0.4985

Formula: T = 2π√(L ÷ g)

Step-by-Step Breakdown

1. Values used:

2. Length = 1

3. Gravity = 9.81 m/s²

5. Period = 2.006

6. Frequency = 0.4985Hz

The math behind it

T = 2π√(length ÷ g). Mass and swing amplitude don't affect it (for small angles).

1 m pendulum → period 2.01 s.

Why mass doesn't matter?

Gravity accelerates all masses equally, so it cancels out.
