  • The Mystery of c^2 in Einsteins Famous Formula E=mc^2 Explained
    Why c^2 in "e=mc^2"? Ok, i'v got that e=mc^2 meens some mass at max possible speed will equal max possible energy But max possible speed is c, not c^2 Nothing can have speed greater than speed of light, isn't it?
  • Deriving the Expression for Total Energy . . . - Physics Forums
    Discussion Overview The discussion focuses on the derivation of the expression E = γ m c 2, exploring its implications for total energy in different frames of reference Participants examine the relationship between rest mass, kinetic energy, and the effects of relativistic motion, as well as various methods of deriving the equation Discussion Character Exploratory Technical explanation
  • E=MC^2 - easy explanation for kids - Physics Forums
    Been lurking on these threads looking for easy explanations of E=mc2 as it relates to nuclear fission weapons Shame, SHAME, to yall advanced physicists who dismiss and disrespect and flame amateurs on other threads asking for easy examples for kids I'm a humanities teacher teaching
  • E=mc^2 Explained: Momentum and c - Physics Forums
    The discussion revolves around the relationship between energy and momentum as expressed in the equation E = pc, particularly in the context of E = mc^2 Participants explore the implications of this relationship for particles with zero rest mass, such as photons, and how it applies to scenarios involving massive radiation The conversation includes technical reasoning, conceptual
  • Derive E=mc^2: Kinetic Energy, Photons, Lorentz-Transformations
    The discussion revolves around the derivation of the equation E=mc^2, exploring various approaches including kinetic energy, relativistic momentum, and Lorentz transformations Participants express interest in finding derivations that do not rely on certain advanced concepts like Taylor expansion or electromagnetic theory
  • Einstein did not derive E =mc2 first - Physics Forums
    In 1952, H E Ives [12] stressed that Einstein’s derivation of the formula E=mc^2 is fatally flawed because Einstein set out to prove what he assumed Sharma [13] in 2003 extended E=mc^2 to E =Ac^2m, where A is conversion co-efficient and can be equal, less or more than one, depending upon inherent characteristics of conversions process in nature
  • How did E=mc^2 contribute to the atomic bomb? - Physics Forums
    E=mc 2 really didn't contribute to the atomic bomb, however, it does describe an equivalence between energy and matter When a heavy atom fissions, the sum of the masses of the fission products (and the two or three neutrons released) are less than the mass of the original excited fissile atom
  • E=MC^2 Explained: Photon Mass Energy - Physics Forums
    A photon has “zero” rest mass, but it does have Energy, But with zero Mass , E=MC^2 yields E=0 I am confused !
  • How does E=MC^2 convert to Joules? - Physics Forums
    The discussion focuses on the conversion of energy from the mass-energy equivalence formula E=MC^2 into joules It clarifies that mass must be measured in kilograms for accurate conversion, as 1 joule is equivalent to 11 1265 femtograms (11 1265x10^-18 grams) The speed of light, measured in meters per second, is also a critical component in this conversion process The reference to Wikipedia
  • Derivation of E=pc E=MC2: Which Came First? - Physics Forums
    I have seen E=pc used to derive E=MC2 I have seen E=MC2 used to derive E=pc This is circuitous Which came first and how is E=pc derived?
