Einstein Mass-Energy Equation: Will Mass Change?

In summary, the theory states that when an object is moving in the speed of light, it will lose mass and the lost mass will transform into energy.

according to the theory, when an object is moving in the speed of light, the object will lose it mass and the lost mass will transform into energy.so when the object is moving,if we provide the same energy the object losses to it, will the mass of the object changes?

Your initial premise about relativity is in error. No object with mass can achieve the speed of light.

But accoring to the equation E=mc^2 , isn't that c is refer to the speed of light?

Yes. But you cannot deduce from the formula what you have tried to deduce.

But isn't the particles losing it's mass when it is traveling in he speed of light?

No.
Massless particles (bosons), such as photons, always travel at the speed of light.
Massive particles (fermions), such as electrons or protons, can never reach the speed of light.

You can annihilate massive particles, which will release a burst of photons, and those photons will move away from the interaction at the speed of light. But you don't start with massive particles and accelerate them to c.

OK, thanks dude,but i wanmaask if eectroms and protons will lose mass when they approch8ngthe sped of light?

No. Particles gain mass (more precisely, they gain energy, which is one possible meaning of the term "mass"--usually the term "relativistic mass" is used for this) as they approach the speed of light. Please review the following links for more information:

FAQ: Einstein Mass-Energy Equation: Will Mass Change?

What is the Einstein Mass-Energy Equation?

The Einstein Mass-Energy Equation, also known as E=mc², is a famous equation derived by Albert Einstein in his theory of general relativity. It states that the energy of a particle (E) is equal to its mass (m) multiplied by the speed of light squared (c²).

Does the Einstein Mass-Energy Equation mean that mass can change?

Yes, according to the equation, mass and energy are equivalent and can be converted into each other. This means that under certain conditions, mass can be converted into energy and vice versa. However, the amount of energy produced from a certain mass is enormous, which is why we don't see mass changing in everyday situations.

Can mass change in a closed system?

No, the law of conservation of mass states that mass cannot be created or destroyed in a closed system. This means that in a closed system, mass cannot change into energy or vice versa. Therefore, the Einstein Mass-Energy Equation does not apply in closed systems.

How is the Einstein Mass-Energy Equation used in real-world applications?

The Einstein Mass-Energy Equation is used in various fields such as nuclear physics, astrophysics, and particle physics. It is used to calculate the energy released from nuclear reactions, understand the behavior of particles in accelerators, and study the formation of stars and galaxies.

Is the Einstein Mass-Energy Equation still relevant today?

Yes, the Einstein Mass-Energy Equation is a fundamental equation in modern physics and is still used in various applications and experiments. It also serves as the foundation for the development of other equations, theories, and technologies.
