![]() Rest energy is large because the speed of light c is a large number and \boldsymbol, and then use it to determine the relativistic kinetic energy. We do not notice this energy, because it is generally not available. This is an enormous amount of energy for a 1.00 gram mass. Einstein showed that the law of conservation of energy is valid relativistically, if we define energy to include a relativistic factor. The first postulate of relativity states that the laws of physics are the same in all inertial frames. The altered definition of energy contains some of the most fundamental and spectacular new insights into nature found in recent history. All of these relationships are verified by experiment and have fundamental consequences. Its not a real movie or real reaction, just a meme video I believe. The fake production companies start out their logo with what seems like the start of a movie, but eventually just fades into their logo. ![]() As a consequence, we learn that several fundamental quantities are related in ways not known in classical physics. Ive tried googling so many variations of this, but its a funny video of someone watching the intro credits of a movie. Relativistic energy is intentionally defined so that it will be conserved in all inertial frames, just as is the case for relativistic momentum. Relativistically, energy is still conserved, provided its definition is altered to include the possibility of mass changing to energy, as in the reactions that occur within a nuclear reactor. We know that classically the total amount of energy in a system remains constant. Not only does energy have many important forms, but each form can be converted to any other. Nuclear reactors are proof of the conservation of relativistic energy.Ĭonservation of energy is one of the most important laws in physics. Accomplishing this requires an understanding of relativistic energy.

In this process, a relatively small mass of fuel is converted into a large amount of energy. The National Spherical Torus Experiment (NSTX) has a fusion reactor in which hydrogen isotopes undergo fusion to produce helium.
