In 2010 PBS aired a short series called Circus. Circus was a documentary about the Big Apple Circus. The show took viewers behind the scenes of a traveling circus production. All six of the episodes are currently available to watch online. Today, through a Tweet by Danny Nicholson I learned that the Circus website offers some short circus-based physics lessons.
Circus Physics is a series of eight short videos. Each of the videos features a circus act that demonstrates a basic principle of physics. Each video clip is accompanied by text and image explanations. I’ve embedded the Newton’s Laws of Motion video below.
