## Period of Pendulum

A pendulum that vibrates can be classified as ‘simple pendulum’ and ‘physical pendulum’. A simple pendulum is a case in which the angular motion of an object can be ignored, such as…

## Resonance

Find the frequency at which the amplitude is maximum at each rod. What is the relationship between thickness and resonant frequency?

## Spring Pendulum

What are the factors that affect the cycle of the spring pendulum? (The effect of reducing the amplitude by friction is ignored.)

## Gravity Train

What happens if you punch a long hole in the earth and then drop the object? By the way, is this really possible? How long does it take to get to the…
