When a musician strums a guitar, the vibration of the strings creates sound waves that human ears hear as music. When a guitar string is plucked, it moves a certain distance, depending on how hard the ...

A basic pendulum is a mass at the end of a string that swings back and forth. It seems simple, and it appears in most introductory physics textbooks. But it's not a trivial problem to solve for the ...

Check out Dr. Bob Grober on YouTube. I heard the term “harmonic oscillator” a few years ago and was lost until I found out it was simply a pendulum. Understanding how a pendulum works and how we can ...

This module expands on the capabilities for teaching using a Pendulum. A pendulum by itself can provide valuable insight into harmonic motion and the relationship between frequency and period. It can ...

A ball is suspended from a pivot so that it can swing freely. The length of the pendulum is adjustable. For small amplitude, the motion of the pendulum as a function of time is approximately simple ...
