WebThis is, of course, the famous equation E=mc 2, however, it highlights an important point; mass is simply another form of energy, namely, the energy that any particle has at rest.This IS the fundamental definition of mass. Based on this, we can also intuitively reason why a photon does not have mass and it comes from another prediction of special relativity. WebSince light has no mass, you may be tempted to say that light has no momentum. Additionally, everyday experiences may seem to confirm that light has no momentum … Web1 de fev. de 2016 · The use of words can make a lot of confusion. Unfortunately, the word "mass" has been used in two different ways in physics. One was the way Einstein used it in E=mc 2, where mass is really just the same thing as energy (E) but measured in different units.This is the same "m" that you multiply velocity by to find momentum (p), and thus … cscs mock test training
