I was remembering the equation E=MC2. So as per me Rest Mass is nothing but Energy that is stationary. Am I right?
Rest mass and rest energy are equivalent and remain proportional to one another. I am not talking about object that is moving here.Simon Bridge said:Note: E=mc2E=mc^2 just means that mass is a form of energy.
... this is correct. What I want you to realize is that "rest mass" does not refer only to "energy that is stationary". In the context of Einstein's relativity there is no absolute motion, so there is no absolute for "stationary" either. The word "stationary" must be used with a reference frame. Stationary with respect to what? Moving with respect to what? So when you said:Rest mass and rest energy are equivalent and remain proportional to one another. I am not talking about object that is moving here.
... you forgot to say what it is stationary with respect to.Rest Mass is nothing but Energy that is stationary.
... the kg and the J are the SI units for mass and energy respectively. These are not the only units. Speed is also measured in miles-per-hour, mass in pounds, and energy in ergs, for example.Now E=MC2. Energy and mass are equivalent and the "C2" is the conversion factor because the mass has to be converted into units of Energy. Mass is measured in Kilograms and Energy is measured in Joules. So to convert Kilograms to Joules "C2" would be used.
Rest mass is also known as invariant mass and is given by ##m^2c^2=E^2/c^2-p^2##. So if momentum is 0 then that reduces to the famous ##E=mc^2##.avito009 said:I was remembering the equation E=MC2. So as per me Rest Mass is nothing but Energy that is stationary. Am I right?

The equation E=MC2 is known as the mass-energy equivalence formula, where E represents energy, M represents mass, and C represents the speed of light in a vacuum. It states that energy and mass are interchangeable and are related by the speed of light squared.
Rest mass is the mass of an object when it is not moving. It is also referred to as invariant mass or proper mass. It is a fundamental property of particles that does not change with velocity or location.
E=MC2 shows the relationship between energy and mass, stating that energy is equal to the mass of an object multiplied by the speed of light squared. This equation applies to both rest mass (when an object is not moving) and relativistic mass (when an object is moving at high speeds).
E=MC2 is important because it explains the relationship between mass and energy, which is a fundamental concept in physics. It has also been used in various technological advancements, such as nuclear energy and nuclear weapons.
Yes, E=MC2 can be used to convert mass into energy. This is the basis of nuclear reactions, where a small amount of mass is converted into a large amount of energy. However, this conversion is only significant for very large masses, such as those found in atomic nuclei.
