As a pure number, c = 1 c = 1. There are a few things that travel at speed 1, including light and gravity. Light was simply the first one that we discovered, which is the only reason c c is called the "speed of light."
8 Νοε 2012 · I have always wondered why the energy of a photon in vacuum is equal to E = pc (where p is the momentum of the photon, and c is the speed of light in vacuum) and not E = 1/2 pv (where for a photon v = c) as is the case for the kinetic energy of any moving mass.
23 Ιουλ 2024 · Explore Einstein's famous E=mc² equation with our calculator and understand the mass-energy equivalence easily.
The equation [latex]\boldsymbol{E^2 = (pc)^2 + (mc^2)^2}[/latex] relates the relativistic total energy [latex]\boldsymbol{E}[/latex] and the relativistic momentum [latex]\boldsymbol{p}[/latex]. At extremely high velocities, the rest energy [latex]\boldsymbol{mc^2}[/latex] becomes negligible, and [latex]\boldsymbol{E = pc}[/latex].
This is Einstein's celebrated equation: E = mc 2 for the important case of one particular sort of energy, the kinetic energy of motion. We shall see shortly that it can be generalized to all forms of motion.
This energy is described by E = mc 2, where c is the speed of light. In terms of density, m = ρV , where ρ is the volumetric mass density, V is the volume occupied by the mass. This energy can be released by the processes of nuclear fission (~ 0.1%), nuclear fusion (~ 1%), or the annihilation of some or all of the matter in the volume V by ...
5 Φεβ 2019 · vc(t) = 1 −e− t RC v c (t) = 1 − e − t R C. So basically e e appears because it's the base of the exponential function that solves the differential equation df(t) dt = f(t) d f (t) d t = f (t), and the RC R C term appears because of the way current relates to capacitor voltage in the circuit.
