The Real Meaning of E=mc Squared

The video explores the concept of mass and energy, focusing on Einstein's famous equation E=mc². It explains how mass is not just the sum of its parts but also depends on the arrangement and movement of those parts. The video uses examples like wind-up watches and flashlights to illustrate how energy contributes to mass. It also discusses the concept of negative potential energy in atoms and how this affects their mass. The video concludes by emphasizing that mass is a property of energy, not a measure of matter.

Discuss the concept of potential energy being negative in the context of a hydrogen atom.
