It allows you to calculate the corresponding energy.
The mass of an object
Energy equals mass times the speed of light squared. Energy and mass are equivalent.
Energy equals mass times the speed of light square.
Energy equals mass times the SPEED of light squared
That energy and mass are just two forms of the same thing.
E=ENERGY = M=MASS C=SQUARED 2=TIMES ITSSELF
If you add the exact mass of the protons, neutrons, and electrons in an atom you do not get the exact atomic mass of the isotope. The diference is called the mass defect. The difference between the mass of the atomic nucleus and the sum of the masses of the particles within the nucleus is known as the mass defect.
E=Energy m=mass c=speed of light -Thunder
value of m is simply mass or the object total mss
Nuclear binding energy is the energy required to hold the nucleus together. The mass defect is the difference between the mass of a nucleus and the sum of the masses of its individual protons and neutrons. The mass defect is converted into nuclear binding energy according to Einstein's famous equation, E=mc^2, where E is the energy, m is the mass defect, and c is the speed of light.
nuclear fusion
E = MC2; energy is equal to a quantity of matter. When protons (and neutrons) combine in an atomic nucleus, the resultant mass is less than that of the individual particles. This is the mass defect, and the 'missing' mass is a result of the energy binding the particles together. The larger the mass defect for a particular atom (isotope), the larger the amount of nuclear binding energy.
