Question

Disprove the following:
1. E=mc square

Answer 1

Explanation:

the equation is dimensionally correct because all the terms have dimensions of speed. (c)E = mc2, where E is energy, m is mass and c is the speed of light. So the equation is dimensionally correct as all terms have dimensions of energy.

In the equation, the increased relativistic mass (m) of body times the speed of light squared (c2) is equal to the kinetic energy (E) of that body. Proof of Albert Einstein's special-relativity equation E = mc2. ... In special relativity, however, the energy of a body at rest is determined to be mc2

Answer 2

this equation is correct only when an object is not moving with respect to u .

it is wrong when an object is not moving,
