Steps to Solve Einstein Theory of Relativity

These are the steps to find the relationship between mass and energy of an object. Albert Einstein proved that mass and energy are equivalent.

  • Let us take the mass of an object
  • Find the square of the speed of the light.
  • Multiply the square by the mass of the object to get the energy.

E=mc2 Special Relativity Equation

In the year 1905, Einstein stated that the law of conservation of energy and law of conservation of mass are same. And the mass, energy are equivalent.

The mass energy equivalence equation an be read as E equals m squared. It is given as

E = mc2

Where,

E is the energy of the object

m is the mass of the object

c is the speed of light and value is 299,792,458 m/s

Example

Question: Calulate the Einstein mass energy if the mass is 15 kgs.

Solution:

Given that

Mass of the object m = 15 kgs

Speed of the light c = 3 x 108 m/s

Energy of the object E = mc2

E = 15 x (3 x 108)2

E = 15 x 9 x 1016

= 135 x 1016

Therefore, energy of the object is 135 x 1016

Frequently Asked Questions on E=mc2 Calculator

1. How to calculate E=mc2?

E=mc2 is the Einstein's mass-energy equivalence equation. It is used to find the amount of energy that is equivalent to the given mass. Multiply the mass of the object by square the speed of the light to obtain the energy.


2. What is the formula of relativity?

The relativity formula is E = mc2. Where E is the energy, m is the mass and c is the speed of the light.


3. How to solve mass in E=mc2?

We know that mass energy equivalence formula is E = mc2. From this, mass m = E/c2. Divide the energy by the square of the speed light to get the mass of an object.


4. What is meant by Mass Energy Equivalence?

The mass-energy equivalence is the consequence of Albert Einstein's theory of special relativity. This law states that the mass of an object can be converted into energy and vice-versa. The conversion formula is E = mc2.
