Why don’t you weigh less when you’re descending and more when you’re ascending in an elevator?

Sure, I could tell you the answer, but then you’d miss out on this easy-to-understand animated video by physicist Carol Hedden and animator Andy London for TED.  Hedden explores the relationship between gravity, weight, and relative motion, using a moving elevator to explain the fascinating physics.

You can head over to the TED lessons page for more information and resources for learning all about the mysterious force that we call gravity.
