Learn how to create a simple DIY pendulum using a ping pong ball and everyday household materials in this easy step-by-step ...

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 ...

Nudge something away from where it was at rest, and often it will push back. And then overshoot. From atoms to bridges to wheeled luggage, much of the world is in simple harmonic motion Yesterday my ...

Explore the equations of motion for a pendulum using the polar coordinate system! This video breaks down how pendulum dynamics can be described with angular displacement, radial constraints, and ...

Introduction Did you know that playground swings can provide a good lesson in physics—as well as lots of fun? The back-and-forth motion of a swing is an example of a pendulum. We see pendulums in ...
