Q:

What does "E=mc²" mean?

A:

Quick Answer

In the equation E=mc², e stands for energy, m stands for mass and c² stands for the speed of light squared. First proposed by Albert Einstein, this equation demonstrates that energy and matter are interchangeable.

Full Answer

Einstein first published the formula in 1905, which is often called his "miracle year," according to the Encyclopaedia Britannica. It was part of a paper titled “Does the Inertia of a Body Depend Upon Its Energy Content?”

The equation established the first mechanism to explain the energy source of stars such as the sun, and it opened the way for new advances in nuclear power and nuclear medicine.

  • Q:

    What is an example of E=m*c^2?

    A:

    One example of E=m*c^2 is the equation that demonstrates the conversion of 1 kg of matter into 9.0*(10^16) J of energy. Examples of E=m*c^2, or the mass-energy equivalence equation, can be found in physics classrooms in equations that convert matter to energy and vice versa. The formula is based on the theory that matter is directly proportional to energy.

  • Q:

    What is "E=mc2"?

    A:

    "E=mc2" is one of Albert Einstein's most famous equations, which relates the energy and mass of an object. An important thing to note is that since mass is multiplied by the speed of light squared, even small amounts of mass can create large amounts of energy.

  • Q:

    In which way is a photon of blue light similar to a photon of red light?

    A:

    Light from blue and red photons has energy but no mass, has no electrical charge and travels at the speed of light. All photons share these properties, no matter their energy level. A photon’s color comes from its wavelength, with blue having a higher value than red.

  • Q:

    What does "E=mc2" mean?

    A:

    Albert Einstein's formula "E=mc2" means energy equals the mass of an object multiplied by the speed of light squared. His theory means that the mass of an object, no matter how small, can be transformed into a tremendous amount of energy.
