Question: In Einsteins’s famous equation E=mc², what does the “c” stand for?

Answer: Widely considered the most well-known mathematical calculation in the world, E=mc² is the signature discovery of Albert Einstein. His famous formula is known as the special-relativity equation. In the equation, “m” is the mass of an object, “c” is the speed of light, and “E” is energy. Thus, the mass (m) of a body times the speed of light squared (c²) is equal to the kinetic energy (E) of that body. On the most basic level, the equation says that mass and kinetic energy are equal, since the speed of light squared is constant. In other words, mass can be changed into energy, and energy can be changed into mass.

1  E = mc² | Einstein’s Relativity
http://facebook.com/ScienceReason … Albert Einstein’s Theory of Relativity (Chapter 4): E = mc² (Mass-Energy Equivalence) In physics, mass-energy equivalence is the concept that the mass of a body is a measure of its energy content. In this concept the total internal energy E of a body at rest is equal to the product of its rest mass m and a …

4In Einsteins’s famous equation E=mc², what does the “c” stand for Speed of light
E = mc 2, equation in German-born physicist Albert Einstein’s theory of special relativity that expresses the fact that mass and energy are the same physical entity and can be changed into each other. In the equation, the increased relativistic mass (m) of a body times the speed of light squared (c 2) is equal to the kinetic energy (E) of that body.. In physical theories prior to that of …

5In Einsteins’s famous equation E=mc², what does the “c” stand for Speed of light
c represents the speed of light. The c comes from the latin word celeritas which means speed or swift. c is approximately 90 billion kilometers 2 per second 2. In the equation, the value of c is “squared” or has the superscript 2 (above the line). That simply means c is multiplied by itself. It can also be represented as c x c or c • c or cc.

8In Einsteins’s famous equation E=mc², what does the “c” stand for Speed of light
E = MC ^ 2 is perhaps the most famous equation of all time. It stands for E(negery) = Mass times the Speed of Light (C) squared. What this means is that if you take the mass of an object and multiply it by the speed of light (2.9 x 10^8 metres per second) you will then have calculated the ammount of energy.
