e, or Euler's number, is roughly equal to 2.718. For more information, see the related link.

e is also used to refer to other properties. In the following famous equation, e refers to energy:
enegy= mass x the speed of light squared which for short is e=mc2
E in the equation "E = mc^2" refers to "Energy".
m refers to mass.
c is the speed of light.

What is e in e equals mc2?

E=mc2 means energy=mass multiplied by the speed of light squared.

What does c equal if E equals mc2?

In the equation E=mc2 'c' is equal to the speed of light (in a vacuum) or 2.997*108. or... 186282.397 miles per second 670616629 miles per hour Or if you're metric 1

Why e equals mc2 is necessary?

e=mc2 is a constant. so you can use it in a variety of equations without having to do all the math up to that point. basically it helps us measure astronomical numbers. -- (se

What were the needs for E equals MC2?

There was no particular 'need' for [ E = mc2 ], and it was not the goal, the purpose, or the main result of the work during which it was discovered. It just sort of popped

Who formulated the E equals mc2?

e = mc2 is a famous equation by Albert Einstein (who, along with with Sir Isaac Newton, is probably the most famous physicist to have lived). It tells us that energy is equal

What is Einstein's E equals mc2?

e=mc^2 pretty much is a relation between mass (m) and energy (e) where c = speed of light. Pretty much, as something goes faster, it gains slightly more mass. It really has no
