what does the C square stand for in E=MCsquare.?

Answer 1

c is the speed of light: 3 * 10^8 meters/second

c-squared is: 9 * 10^16 meters^2/seconds^2

(^2 means squared).

When you multiply meters^2 / seconds^2 times mass in kilograms you get:
kilograms * meters ^2 / seconds ^2
which are the units for energy, also called "Joules".


.

Answer 2

The speed of light times itself.

Answer 3

Energy= (Matter * Speed of Light)Squared

Answer 4

C stands for the speed of light - 300,000 meters per second. When used in this equation it is a constant that equals 90,000,000,000 m^2/s^2

Energy = mass x C^2

so,

Energy = kg (m^2/s^2)

1 Newton is (kg m/s^2)
so the Energy is measured in Newton meters (or Joules)
If you want English units,
1 Joule = 0.737562 foot-pounds(force)

But this pound is pound of mass. A pound of force is (pound feet / second^2), so you end up with;

Energy = foot-pounds(force)

So if you convert 1 pound of something entirely into Energy, you get;

Energy = (1 pound (force) / (32.2 ft / sec^2)) X (34596000000 ft^2 / s^2)

(I had to divide mass by the acceleration of gravity, 32.2 ft / s^2, in order to convert pound (force) into pound (mass)).

Energy = 1,074,409,938 foot-pounds (force)

Answer 5

E=energy
M=mass
C=speed of light

Answer 6

the speed of light

Answer 7

c = speed o' light
