The formula E = mc 2 was first known when it was introduced in a paper by Albert Einstein in 1905 and became the most famous formula that set the stage for a breakthrough in science and technology later. In the formula E=mc 2 , E is energy, m is mass and c is the speed of light in a vacuum. [1] X Source of Research Even people with no background in physics have heard of this formula and are, to some extent, aware of its influence, however, most of the time. that number has not grasped the true meaning of this formula. Simply put, this is a formula that shows the relationship between energy and matter: especially the fact that energy and matter are two different forms of the same thing.

Steps
Understand the formula
- The speed of light c is a constant that is approximately 3.00×10 8 meters per second. In Einstein’s theory of relativity, c 2 acts as a unit-changing factor rather than a constant. Since energy is measured in units of Joule (J) or kg m 2 s -2 , the use of c 2 is the result of dimensional analysis which ensures that the relationship between energy and mass is one-dimensional .
- Energy cannot be created or destroyed, it can only be converted from one form to another. For example, coal has a lot of potential energy that can be converted into heat when burned.
- There are also a few other definitions of mass. “Constant mass” and “relative mass” are two of them. Constant mass, as the name implies, is mass that remains constant under all circumstances. Meanwhile, the relative mass depends on the velocity of the object. The mass in the formula E = mc 2 is constant mass. This is an important point contrary to the popular belief that the mass of an object does not change with increasing speed.
- Remember that mass and weight are two different concepts. Weight is the gravity of an object, and mass is the amount of matter that makes up the object. Mass changes only when the object is physically changed, while weight changes depending on the gravity of the environment. Mass is measured in kilograms (kg), weight is measured in newtons (N).
- Similar to energy, mass is neither created nor destroyed, but only converted from one form to another. For example, an ice cube may melt into a liquid form but its mass does not change.
Applying the formula in practice
- Getting energy in this way is not only inefficient but also harmful to the environment.
- Nuclear energy is also based on this principle. Nuclear reactors cause fission (which causes atoms to separate), and humans will recover the energy released from that fission.
- Positron tomography (PET) uses radiation to see the inside of the body.
- Based on this formula, scientists have developed communication technologies from satellites and autonomous rovers.
- The age of the artifact is determined by the radiocarbon method, which is based on the radioactive decay process according to the formula E=mc 2 .
- Nuclear energy is a cleaner and more efficient source of energy than traditional energy sources that people still use.
