What does E=mac2 mean( by Albert Einstein).

E=mc(squared) is the formula for conversion of matter to energy. The amount of energy released is equal to the amount of matter involved times the speed of light squared. A quick calculation shows that a very small amount of matter equals an enormous amount of energy. This formual was the basis for the atomic bomb.

Nothing to do with iMacs or big Macs lol. It's E=Mc2

E=mc^2
E is energy
m is mass
c is the speed of light (roughly 3 * 10^8 meters/second)

Einstein didn't invent the Mac... Steve Jobs did.

RIP!

http://www.chaospark.com/science/emc2.htm seems to explain this E=MAC2 relationship.

START QUOTE from harry@chaospark.com:

Energy is (force)x(distance). Force is (mass)x(acceleration). So energy is (mass)x(acceleration)x(distance) or (pounds)x(32 ft/sec 2 )x(ft) or (pounds)x(32 ft 2 /sec 2 ). This is (mass)x(speed) 2 just like the right hand side of E = MC 2 .

The speed of light is 186,000 miles/sec. We want ft/sec so (186,000)x(5,280(ft/mile)) = 984,000,000 ft/sec. Now this enormous number must be squared! The result is around 967,000,000,000,000,000. To get energy in ft-lb we must divide by the acceleration of gravity (32) to get 30,000,000,000,000,000.

So it appears the acceleration due to gravity is not a significant portion of the equation and can be ignored. It leads me to wonder what would be the "real world result" of the equation if the acceleration approached or reached zero ????

Is it possible to have zero acceleration in our universe considering that the expansion of the universe is accelerating?

Eating two Big Macs is better than one.

Share your answer...

headache.

If this were so it might mean Energy = Mass x Acceleration x Speed of Light Squared
