E=mc² está Incompleta

The video tutorial explains the famous equation for mass and energy, highlighting that it only applies to objects with mass that are not moving. It introduces the complete equation, which includes momentum, and uses the Pythagorean theorem to illustrate it. The tutorial also covers massless particles like photons, showing that their energy is equal to their momentum times the speed of light. Finally, it discusses how an object's speed approaches the speed of light as its momentum increases, but never reaches it due to the presence of mass.
