Physics - E=mc^2

The Energy in E=mc^2 is measured in what form?

Joules

E=mc^2 solves what?

This simple algebraic formula represents the correlation of energy to matter (energy equivalence of any given amount of mass).

E=mc^2 stands for what?

Energy = mass x the speed of light squared

What is the speed of light?

299 792 458 m / s

The mass in E=mc^2 is measured in what?

Kilograms or grams

and why does the speed of light need to be squared in E=mc^2?

The reason is that kinetic energy, or the energy of motion, is proportional to mass. When you accelerate an object, the kinetic energy increases to the tune of the speed squared. You'll find an excellent example of this in any driver's education manual: If you double your speed, the braking distance is four times longer, so the braking distance is equal to the speed squared

Einstein demonstrated that mass and energy are the same thing. True or False

True
