E=mc2 is Incomplete

The video explains the relationship between energy, mass, and momentum using the equation E squared equals MC squared squared plus P * C ^2. It describes how this equation applies to objects with mass and those that are massless, like light. The video uses a right triangle analogy to illustrate the concepts and explains why objects with mass cannot reach the speed of light due to the properties of the triangle's hypotenuse.

Explain the relationship between the energy of a massless particle and its momentum.

Why can an object's velocity never quite reach the speed of light?
