# Mini-Quiz: Equations for a Simple Pendulum

by Ron Kurtus (revised 17 December 2016)

Take this Mini-Quiz to check your understanding of the lesson material.

1. What is the period of motion when the string length is 4 m?

About 4 seconds

About 2.8 seconds

About 4 minutes

2. If the period of a pendulum is 2 seconds, what is its frequency?

2 Hz

You need more information to determine the frequency

0.5 Hz

3. How does a pendulum on the Moon compare with one on Earth?

It doesn't work, because there is no air on the Moon

Its frequency would be less because gravity (g) on the Moon is less than on Earth

Its frequency would be greater because gravity (g) on the Moon is more than on Earth

If you got all three correct, you are on your way to becoming a Champion in Physics. If you had problems, you had better look over the material again.

Be amazed by things you see
