Newton’s Third Law of Motion. Many thanks to Kevin Zhang, today's Flipping Physics Correspondent in China and to Ari Morris for letting me use a video of my kids at The Ann Arbor Hands-On Museum from 2007. That’s right, this video spans the globe, from my driveway to China!
Yep, I make physics videos in the hope that you can learn physics. If you are a physics teacher, I am very hopeful that you will want to use them to help flip your physics class.
