If you mean in the equation E=mc2, the "m" stands for mass.
1.00 M
The mass of an object
It was NOT discovered , but calculated by Albert Einstein. E= mc^2 Where E = energy 'm' = mass 'c' is the speed of light. Notice how it is closely related to mechanical energy K.E. = (0..5)m v^(2)
E=mc2 E=energy m=mass c=speed of light Einstein's equation states that Energy equal mass times the speed of light squared
Albert Einstein's father was Hermann Einstein and his mother was Pauline Einstein.
Albert Einstein is famous for mathematics e=m
1.00 M
m is mass in the equation.
5' 9¼" (1.76 M)
E=m(c*c)
The mass of an object
mass
Albert Einstein. The Equation is E = m*c^(2) That is E is Energy m is mass c^2 is speed of light squared.
E = MC2 Energy = Mass * 300,000 m/s2

E=mc2 in which E is energy, m is mass, and c is the space of light
