Friends, you are famous for Einstein **Equation E=mc2 **Must have heard about. This small equation has the power to shake the world. From this small equation, we came to know that converting one pound of matter into energy will produce energy equivalent to burning 7,000,000 tons of dynamite. In today’s article we will learn about this equation.

In 1905, Einstein established a relationship between mass and energy, which is also called Einstein’s mass-energy relationship. propounded by einstein **“Theory of Relativity” **Prior to this there was a concept that mass and energy are two different quantities and **Conservation of energy** And **mass conservation(conservation of mass) **There are two separate independent rules.

### Einstein’s famous **Equation E=mc2**

In 1905, Einstein proved by propounding his ‘theory of relativity’ that mass and energy are not independent of each other, but both are related to each other and every substance has energy due to its mass.

If the mass of an object is m and the velocity of light is c, then the energy produced by this mass is E = mc^2 or if there is a loss of m in the mass of an object, then the amount of energy generated due to this lost mass** (Δm)c^2** it occurs.

**Mass conservation** And **Energy conversion **Not two different rules but two forms of the same rule and that rule** (mass + energy)** The law of conservation means that the total magnitude of (mass + energy) in the universe is conserved. The equation E = mc^2 is called Einstein’s mass-energy equation. Earth is constantly receiving energy from the Sun in the form of heat, as a result of which the mass of the Sun is continuously decreasing.

That is, the mass of the Sun is constantly being received by the Earth in the form of energy. According to the data, the Earth is receiving 4 x 10^26 joules of energy per second from the Sun, as a result of which its mass is decreasing at the rate of about 4x 10^26 kg per second. But the mass of the Sun is so much that it will continue to give energy to the Earth at the same rate for one thousand crore years.

## Mass defect and nuclear binding energy

The mass of the nucleus of an atom, present in it **neutrons **And **protons **is always less than the sum of the masses.

This decrease in the mass of the nucleus is known as ‘mass loss’. Therefore, it is clear that when protons and neutrons combine to form the nucleus, some of the mass is lost. This lost mass is converted into energy.

If m mass disappears, then the amount of energy associated with it according to Einstein **Δmc^2 **And this energy binds nuclear particles, neutrons and protons together.

Therefore, the same amount of energy is required to break the nucleus into neutrons and protons. This energy is called the nucleus** ‘binding energy’** it is said. copy of the nucleus **Nucleon (proton + neutron)** The higher the binding energy, the more stable the nucleus is.
