Simple pendulum simulator

A swinging pendulum on Earth, the Moon, Mars or Jupiter. Change its length and how far it swings to see the period, frequency and top speed.

Works in metric or imperial units.

Questions students ask

What is the period of a simple pendulum?

T = 2π√(L/g) for small swings. It does not depend on the mass of the bob.

Does the amplitude affect the period?

Only slightly for small swings; at large angles the period gets noticeably longer.
